Pin Name

Description

Active high enable pin. Connect to VIN if not being used.

GND

Ground pin. Use for heatsinking along with Pin #5.

BYP

Noise bypass pin. Connect a 10nF capacitor (required) between this pin and GND.

Regulator output, supplying a guaranteed 150mA.

GND

Ground pin. Use for heatsinking along with Pin #2.

VIN

Power input pin.

APPLICATION HINTS (Refer to Sheet 1):

(1) C

IN (C3) is needed if the device is far from the supply’s filter capac-

itors, or for operation from a battery. A value of 1.0µF or greater should

be used. C

IN may be tantalum or ceramic.

(2) C

O (C2) should be a 1µF or greater tantalum or ceramic capacitor,

with an Equivalent Series Resistance (ESR) between 10m

Ω and 1Ω

over temperature. Larger value capacitors will improve the overall tran-

sient response.

(3) C

BYP (C1 - required) should be placed as close as possible to pin 3

and ground. A 10nF ceramic capacitor is recommended.

(4) EN may be tied to V

IN if the shutdown feature is not required. Maxi-

mum EN voltage = V

IN.

(5) Connect both ground pins (2 and 5) to ground to maximize heat

conduction.
