NOT RECOMMENDED FOR NEW DESIGN SC1453
150mA Ultra Low Dropout
Regulator with Low Noise Bypass
POWER MANAGEMENT
Description
The SC1453 is a low dropout linear regulator that
operates from a +2.25V 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 may be
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 and the ultra-low profile 5 lead TSOT-23.
