SC1541  
1.0A Low Dropout Voltage  
Regulator with Enable  
POWER MANAGEMENT  
Description  
Features  
The SC1541 is a high performance low dropout positive  
voltage regulator designed for use in applications where  
power management is critical, such as battery powered  
systems.  
‹ Low dropout performance, 1.3V max  
‹ Full current rating over line and temperature  
‹ Fast transient response  
‹ +2% total output regulation over line, load  
and temperature  
‹ 10µA max. quiescent current in shutdown  
‹ Three fixed output voltages  
‹ Line regulation 0.2% max.  
‹ Load regulation 0.4% max.  
‹ SO-8 and TO-263 packages  
Additionally, the SC1541 provides excellent regulation  
over variations in line, load and temperature.  
Outstanding features include low dropout performance  
at rated current, fast transient response, internal  
current limiting and thermal shutdown protection of the  
output device. A very low quiescent current of 10µA in  
shutdown mode reduces power dissipation.  
Applications  
‹ Low voltage microcontrollers  
‹ Switching power supply post-regulation  
‹ Instantly available circuits  
‹ Motherboards  
The SC1541 is available with three different voltage  
options as standard and two package options, SO-8 and  
5-lead TO-263.  
‹ Battery operated equipment

Notes:  
(1) Input and output capacitors should be located close to the device.  
(2) Connect all pins to PCB (SO-8 package) for optimal thermal characteristics.  
(3) Increasing the output capacitor value will improve the overall transient response.  
(4) The device is enabled when VEN = VIN, and shut down when EN is pulled to ground. EN should not be taken higher  
than VIN. A CMOS signal referenced to VIN would be ideal for switching the SC1541 on and off.
