SC5205

150mA Ultra Low Dropout, Low

Noise Micropower Linear Regulator

POWER MANAGEMENT

PRELIMINARY

Revision 1, January 2001

The SC5205 is a 150mA ultra low dropout linear

regulator with a built in CMOS/TTL logic level enable

switch. It is designed specifically for battery powered

applications where low quiescent current and low

dropout are critical for battery longevity.

The SC5205 uses a Semtech proprietary internal PNP

device for the pass element, providing a low dropout

voltage of 165mV at a load of 150mA, while maintaining

a ground pin current of 2750µA.

The output noise is reduced by placing a 10nF capacitor

on pin 4 (bypass).

Each device contains a bandgap reference, error

amplifier, PNP pass element, thermal and current

limiting circuitry and resistor divider network for setting

output voltage.

The SC5205 is packaged in a 5 pin SOT-23 surface mount

package for a very small footprint and it requires only a

1µF capacitor on the output and a 0.01µF on the bypass

pin for a minimum amount of external components.

Notes:

(1) C

IN (C1) is needed if the device is far from the supplys filter capacitors, or for operation from a battery. A value

of 1.0µF or greater should be used. C

IN may be tantalum or aluminum electrolytic.

(2) C

O (C3) should be a 1µF or greater tantalum or aluminum electrolytic capacitor. Larger value capacitors will

improve the overall transient response.

(3) C

BYP (C2 - required) should be placed as close as possible to pin 4 and ground. A 10nF ceramic capacitor is

recommended.

(4) EN may be tied to V

IN if the shutdown feature is not required. Maximum EN voltage = VIN.
