SC1453
150mA Ultra Low Dropout
Regulator with Low Noise Bypass
POWER MANAGEMENT
Description
Features
PRELIMINARY
The SC1453 is a low dropout linear regulator that oper-
ates from a +2.5V to +6.5V input range and delivers up
to 150mA. A PMOS pass transistor allows the low 75µA
supply current to remain independent of load, making
these devices ideal for battery operated portable
equipment such as cellular phones, cordless phones and
personal digital assistants.
The SC1453 has a bandgap reference bypass pin for
very low noise operation - a 10nF (typ.) capacitor is
connected between this pin and ground. Other features
include low powered shutdown, short circuit protection,
thermal shutdown protection and reverse battery
protection. The SC1453 comes in the tiny 5 lead SOT-23
package.

NOTES:
(1) Low duty cycle pulse testing with Kelvin connections required.
(2) Defined as the input to output differential at which the output voltage drops 100mV below the value measured
at a differential of 1V. Not measurable on 1.5V and 1.8V parts due to minimum VIN constraints.
(3) Guaranteed by design.
