19-2584; Rev 0; 10/02

Low-Noise, Low-Dropout, 200mA

Linear Regulator

General Description

Features

The MAX1598 low-noise, low-dropout linear regulator

operates from a 2.5V to 6.5V input and delivers up to

ꢀ 200mA Output Current

ꢀ Low Output Noise: 30µV

RMS

200mA. Typical output noise is 30µV

, and typical

RMS

dropout is only 236mV at 200mA. The output voltage is

preset to voltages from 2.5V to 5V in 100mV increments.

ꢀ Low 55mV Dropout at 50mA Output

ꢀ Low 85µA No-Load Supply Current

Designed with an internal P-channel MOSFET pass

transistor, the MAX1598 maintains a low 100µA supply

current independent of the load current and dropout

voltage. Other features include a 10nA logic-controlled

shutdown mode, short-circuit and thermal-shutdown

protection, and reverse battery protection. The device

also includes an autodischarge function, which actively

discharges the output voltage to ground when the

device is placed in shutdown. The MAX1598 comes in

a thin 5-pin SOT23 package.

ꢀ Low 100µA Operating Supply Current,

Even in Dropout

ꢀ Thermal-Overload and Short-Circuit Protection

ꢀ Reverse Battery Protection

ꢀ Output Current Limit

ꢀ Preset Output Voltages

ꢀ 10nA Logic-Controlled Shutdown

Applications

Cellular, Cordless, and PCS Phones
