+5V/Programmable Low-Dropout

Voltage Regulator

_______________General Description

____________________________Features

♦ 350mV Max Dropout at 200mA

The MAX667 low-dropout, positive, linear voltage regu-

lator supplies up to 250mA of output current. With no

load, it has a typical quiescent current of 20µA. At

200mA of output current, the input/output voltage differ-

ential is typically 150mV. Other features include a low-

voltage detector to indicate power failure, as well as

early-warning and low-dropout detectors to indicate an

imminent loss of output voltage regulation. A shutdown

control disables the output and puts the circuit into a

low quiescent-current mode.

♦ 250mA Output Current

♦ Normal Mode: 20µA Typ Quiescent Current

Shutdown Mode: 0.2µA Typ Quiescent Current

♦ Low-Battery Detector

♦ Fixed +5V (Min Component Count) or

Adjustable Output

♦ +3.5V to +16.5V Input

♦ Dropout Detector Output

♦ 10µF Output Capacitor

The MAX667 employs Dual Mode™ operation. One

mode uses internally trimmed feedback resistors to pro-

duce +5V. In the other mode, the output may be varied

from +1.3V to +16V by connecting two external resistors.

The MAX667 is a pin-compatible upgrade to the

MAX666 in most applications where the input voltages

are above +3.5V. Choose the MAX667 when high out-

put currents and/or low dropout voltages are desired,

as well as for improved performance at higher

temperatures.
