KA7630/KA7631

Fixed Multi-Output Regulator

Features

Description

• Output Currents up to 0.5A (Output1 & 2)

• Output Current up to 1A with External Transistor

(Output3)

• Fixed Precision Output 1 Voltage 5.1V ±2%

• Fixed Precision Output 2 Voltage 8V ±2% (KA7630)

• Fixed Precision Output 2 Voltage 9V ±2% (KA7631)

• Control Signal Generator for Output 3 Voltage (12V ±2%)

• Reset Facility for Output Voltage1

The KA7630/KA7631 is a multi-output positive voltage

regulator designed to provide fixed precision output voltages

of 5.1V, 8V (7630) / 9V(7631) at current up to 0.5Aand 12V

at current up to 1A with external PNP transistor.

An internal reset circuit generates a reset pulse when the

output 1 decreases below the regulated value. Output2 & 3

can be disabled by TTL input. Protection features include

over voltage protection, short circuit protection and thermal

shutdown.

• Output 2,3 with Disable by TTL Input

• Current Limit Protection at Each Output

• Thermal Shut Down

Notes:

1. To check the reset circuit ,the reset output is low to discharge the delay capacitor(=Cd). it’s less than Vo1-0.25V. And the

reset output is high when the delay capacitor voltage linearly increased by the internal current source(10µA) if it’s more than

Vo1- 0.2V. The equation of delay time is same as below. Trd = (Cd × 2.5) / 10µA

2. These parameters, although guaranteed, are not 100% tested in production.
