LP38690-ADJ/LP38692-ADJ

1A Low Dropout CMOS Linear Regulators with

Adjustable Output

Stable with Ceramic Output Capacitors

General Description

The LP38690/2-ADJ low dropout CMOS linear regulators

provide 2.5% precision reference voltage, extremely low

Features

n Output voltage range of 1.25V - 9V

n 2.5% adjust pin voltage accuracy (25˚C)

dropout voltage (450mV 1A load current, V_OUT= 5V) and

n Low dropout voltage: 450mV 1A (typ, 5V out)

n Wide input voltage range (2.7V to 10V)

n Precision (trimmed) bandgap reference

n Guaranteed specs for -40˚C to +125˚C

n 1µA off-state quiescent current

excellent AC performance utilizing ultra low ESR ceramic

output capacitors.

The low thermal resistance of the LLP and SOT-223 pack-

ages allow the full operating current to be used even in high

ambient temperature environments.

n Thermal overload protection

The use of a PMOS power transistor means that no DC base

drive current is required to bias it allowing ground pin current

to remain below 100 µA regardless of load current, input

voltage, or operating temperature.

n Foldback current limiting

n SOT-223 and 6-Lead LLP packages

n Enable pin (LP38692-ADJ)

Dropout Voltage: 450 mV (typ) 1A (typ. 5V out).

Applications

Ground Pin Current: 55 µA (typ) at full load.

Adjust Pin Voltage: 2.5% (25˚C) accuracy.

n Hard Disk Drives

n Notebook Computers

n Battery Powered Devices

n Portable Instrumentation

Typical Application Circuits

20126701

20126702

V_OUT= V_ADJx (1 + R1/R2)

Note: *Minimum value required for stability.
