RT9193

300mA, Ultra-Low Noise, Ultra-Fast CMOS LDO Regulator

General Description

Features

^zUltra Low Noise for RF Application

^zUltra Fast Response in Line/Load Transient

^zQuick Start-Up (Typically 50μs)

^z<0.01μA Standby Current When Shutdown

The RT9193 is designed for portable RF and wireless

applications with demanding performance and space

requirements. The RT9193 performance is optimized for

battery-powered systems to deliver ultra low noise and

low quiescent current. A noise bypass pin is available for

further reduction of output noise. Regulator ground current

increases only slightly in dropout, further prolonging the

battery life. The RT9193 also works with low-ESR ceramic

capacitors, reducing the amount of board space necessary

for power applications, critical in hand-held wireless

devices. The RT9193 consumes less than 0.01μA in

shutdown mode and has fast turn-on time less than 50μs.

The other features include ultra low dropout voltage, high

output accuracy, current limiting protection, and high ripple

rejection ratio. Available in the SC-70-5, SOT-23-5,

TSOT-23-5, WDFN-6L 2x2 and MSOP-8 packages.

RT9193

Applications Information

Bypass Capacitor and Low Noise

Like any low dropout regulator, the external capacitors

used with the RT9193 must be carefully selected for

regulator stability and performance. Using a capacitor

whose value is >1μF on the RT9193 input and the amount

of capacitance can be increased without limit. The input

capacitor must be located a distance of not more than 0.5

inch from the input pin of the IC and returned to a clean

analog ground. Any good quality ceramic or tantalum can

be used for this capacitor. The capacitor with larger value

and lower ESR (equivalent series resistance) provides

better PSRR and line-transient response. The output

capacitor must meet both requirements for minimum

amount of capacitance and ESR in all LDOs application.

The RT9193 is designed specifically to work with low ESR

ceramic output capacitor in space-saving and performance

consideration. Using a ceramic capacitor whose value is

at least 1μF with ESR is >1mΩ on the RT9193 output

ensures stability. The RT9193 still works well with output

capacitor of other types due to the wide stable ESR range.

Figure 1 shows the curves of allowable ESR range as a

function of load current for various output capacitor values.

Output capacitor of larger capacitance can reduce noise

and improve load transient response, stability, and PSRR.

The output capacitor should be located not more than 0.5

inch from the V_OUTpin of the RT9193 and returned to a

clean analog ground.

Connecting a 22nF between the BP pin and GND pin

significantly reduces noise on the regulator output, it is

critical that the capacitor connection between the BP pin

andGNDpin be direct and PCB traces should be as short

as possible. There is a relationship between the bypass

capacitor value and the LDO regulator turn on time. DC

leakage on this pin can affect the LDO regulator output

noise and voltage regulation performance.

Enable Function

The RT9193 features an LDO regulator enable/disable

function. To assure the LDO regulator will switch on, the

EN turn on control level must be greater than 1.2 volts.

The LDO regulator will go into the shutdown mode when

the voltage on the EN pin falls below 0.4 volts. For to

protecting the system, the RT9193 have a quick-discharge

function. If the enable function is not needed in a specific

application, it may be tied to V_INto keep the LDO regulator

in a continuously on state.

Thermal Considerations

Thermal protection limits power dissipation in RT9193.

When the operation junction temperature exceeds 165°C,

the OTP circuit starts the thermal shutdown function turn

the pass element off. The pass element turn on again

after the junction temperature cools by 30°C.

Region of Stable C_OUTESR vs. Load Current

100

For continue operation, do not exceed absolute maximum

operation junction temperature 125°C. The power

dissipation definition in device is :

Instable

P_D= (V_IN− V_OUT) x I_OUT+ V_INx I_Q

The maximum power dissipation depends on the thermal

resistance of IC package, PCB layout, the rate of

surroundings airflow and temperature difference between

junction to ambient. The maximum power dissipation can

be calculated by following formula :

For recommended operating conditions specification of

RT9193, where T_J(MAX)is the maximum junction

temperature of the die (125°C) and T_Ais the maximum

ambient temperature. The junction to ambient thermal

resistance (θ_JAis layout dependent) for TSOT-23-5/

SOT-23-5 package is 250°C/W, SC-70-5 package is

333°C/W, WDFN-6L 2x2 package is 165°C/W and MSOP-

8 package is 160°C/W on standard JEDEC 51-3 thermal

test board. The maximum power dissipation at T_A= 25°C

can be calculated by following formula :

P_D(MAX)= (125°C − 25°C) / 333 = 300mW for

SC-70-5

P_D(MAX)= (125°C − 25°C) / 250 = 400mW for

TSOT-23-5/SOT-23-5

P_D(MAX)= (125°C − 25°C) / 165 = 606mW for

WDFN-6L 2x2

P_D(MAX)= (125°C −25°C) / 160 = 625mW for

MSOP-8

The maximum power dissipation depends on operating

ambient temperature for fixed T_J(MAX)and thermal

resistance θ_JA. For RT9193 packages, the Figure 2 of

derating curves allows the designer to see the effect of

rising ambient temperature on the maximum power

allowed.
