Revision 12/5/2008
Description
linear regulators are designed for portable battery
powered applications, which require low noise
environment, fast enable response time, and low
dropout voltage. Each device contains a bandgap
voltage reference, an error amplifier, a PMOS power
transistor, and resistors for setting output voltage, and
current limit and temperature limit protection circuits.
low cost capacitors and requires a minimum output
capacitor of 1.0μF.
