300mA LDO Linear Regulator with µP Reset

Pin Descriptions

Pin #

Symbol

Function

VIN

LDO voltage regulator input pin. This pin should be decoupled with 1µF or

greater capacitor. See application information.

SHDN

LDO voltage regulator shutdown pin. This pin should not be left floating.

When connected low, all the internal circuitry is powered down. When high, it

is in normal operation.

VDET

Microprocessor reset input power supply pin. It may be connected to V_IN.

Manual reset active low input. A logic low signal on MR asserts a reset condi-

tion. Asserted reset continues as long as MR is low and for a minimum of

150ms after MR returns high.

RESET

Reset output remains low while V_DETis below the reset threshold and remains

so for a minimum of 150ms after V_DETrises above the reset threshold.

GND

BYP

Ground connection pin.

LDO voltage regulator bypass capacitor connection. To improve AC ripple

rejection and decrease LDO regulator self noise, connect a 10nF ceramic

capacitor between this pin and GND.

OUT

LDO voltage regulator output pin; should be decoupled with a 2.2µF or

greater value low ESR ceramic capacitor.
