Preliminary
General Description
The LP2201 is a dual channel, low noise, and low
dropout regulator sourcing up to 250mA at each
channel. The range of output voltage is from 1.2V to
3.6V by operating from 2.5V to 5.5V input.
LP2201 offers 2% accuracy, extremely low dropout
voltage (80mV @ 150mA), and extremely low ground
current, only 25µA per LDO. The shutdown current is
near zero current which is suitable for battery-power
devices. Other features include current limiting, over
temperature, output short circuit protection.
LP2201 is short circuit thermal folded back protected.
LP2201 lowers its OTP trip point from 165°C to
110°C when output short circuit occurs (VOUT <
0.4V) providing maximum safety to end users.
LP2201 can operate stably with very small ceramic
output capacitors, reducing required board space and
component cost. LP2201 is available in fixed output
voltages in the SOT-23-6 package.
