300mA CMOS LDO with RESET Function

AME1300

n Detailed Description

The AME1300 is a combination of a fixed output, low

drop-out regulator and microprocessor monitor. Unlike

bipolar regulators, the AME1300 supply current does not

increase with load current. In addition,V_OUTremains stable

andwithin regulation at very low load currents(an impor-

tant consideration in RTC and CMOS RAM battery back-

up applications) as well as with any type of capacitor

(see below). AME1300 pin functions are detailed below:

Pin Description

RESET output remains low while V_DETis below the reset voltage

threshold, and for 300msec V_DETrises above reset theshold.

RESET

Regulated Voltage Output.

Ground Terminal.

V_OUT

GND

Reference Bypass Input. Connecting a 1000pF to this input further

reduces output noise.

Bypass

Shutdown Control Input. The regulator is fully enabled when a logic

high is applied to this input. The regulator enters shutdown when a

logic low is applied to this input. During shutdown, regulator output

voltage falls to zero, RESET output remains valid and supply current

is reduced to 10 A (typ.)

No connect.

V_IN

Power Supply Input.

Detected input Voltage. V_DETand V_OUTcan be connected together.
