SC1453  
150mA Ultra Low Dropout  
Regulator with Low Noise Bypass  
POWER MANAGEMENT  
Description  
ꢀeatures  
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.  
u “2982/5205” compatible pinout  
u Guaranteed 150 mA output current  
u Very small external components - designed to work  
with ceramic capacitors  
u Low 26µVRMS output noise  
(1.5V option, C = C = 1µ, C = 10nꢀ)

OUT  
BYP  
u Very low supply current  
u Thermal overload protection  
u Reverse battery protection  
u Low power shutdown  
The SC1453 has a bandgap reference bypass pin for  
very low noise operation - a 10nꢀ (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.  
u ꢀull industrial temperature range  
u Very low profile packaging available (1mm max. height)  
u Surface mount packaging (5 pin SOT-23 and  
TSOT-23)  
Applications  
u Battery Powered Systems  
u Cellular Telephones  
u Cordless Telephones  
u Personal Digital Assistants  
u Portable Instrumentation  
u Modems  
u PCMCIA cards
