Description
The LP38691/3 low dropout CMOS linear regulators offer:
Tight output tolerance (2.0% typical)
Extremely low dropout voltage (250 mV @ 500 mA load current, Vout = 5V)
Excellent AC performance with ultra-low ESR ceramic output capacitors
Low thermal resistance of WSON, SOT-223, and PFM packages for full operating current even in high ambient temperature environments
PMOS power transistor eliminates DC base drive current, keeping ground pin current below 100 μA regardless of load current, input voltage, or operating temperature
Features
500 mA low dropout CMOS linear regulators
Stable with ceramic output capacitors
2.0% output accuracy (25°C)
Low dropout voltage: 250 mV @ 500 mA (typ, 5V out)
Wide input voltage range (2.7V to 10V)
Precision (trimmed) bandgap reference
Ensured specs for -40°C to 125°C
1 μA off-state quiescent current
Thermal overload protection
Foldback current limiting
PFM, SOT-223, and 6-lead WSON packages
Enable pin (LP38693)
Applications
Hard disk drives
Notebook computers
Battery-powered devices
Portable instrumentation
