G9293

Global Mixed-mode Technology

Dual, 300mA Low-Dropout Linear Regulators

Features

General Description

Two Low-Dropout-Voltage Regulators

300mA Output Current for Each LDO

Independent Enable Control

Dropout Voltage is 100mV@ 100mA Load

Over-Temperature Protection and Short-Circuit

Protection

The G9293 is a dual, low supply current, low dropout

linear regulator that comes in a space saving TSOT-23-6,

ADFN1.5X1.5-6, TDFN1.6X1.6-6 and TDFN2X2-8 pack-

age. The supply current at no-load is 60µA. In the

shutdown mode, the maximum supply current is less

than 1µA. Output voltage range of the G9293 is from

1.2V to 3.3V. The over-current protection limit is set at

500mA typical. An over-temperature protection circuit

is built-in in the G9293 to prevent thermal overload.

These power saving features make the G9293 ideal

for use in the battery-powered applications such as

notebook computers, cellular phones, and PDA’s.

1.2V to 3.3V Factory-Preset Output

Max. Supply Current in Shutdown Mode < 1µA

Small Ceramic Output Capacitors

400Ω V_OUTDischarge Resistance in Shutdown

Applications

Notebook Computers

Cellular Phones

PDAs

Digital still Camera and Video Recorders

Hand-Held Devices

Bar Code Scanners

These devices feature a shutdown function and are of-

fered in active low with auto discharge. The G9293

comes in a space saving TSOT-23-6, ADFN1.5X1.5-6,

TDFN1.6X1.6-6 and TDFN2X2-8 package.
