LP38690/LP38692  
1A Low Dropout CMOS Linear Regulators  
Stable with Ceramic Output Capacitors  
General Description  
Features  
The LP38690/2 low dropout CMOS linear regulators provide  
tight output tolerance (2.5% typical), extremely low dropout  
voltage (450mV @ 1A load current, VOUT = 5V), and excellent  
AC performance utilizing ultra low ESR ceramic output ca-  
pacitors.  
2.5% output accuracy (25°C)  
Low dropout voltage: 450mV @ 1A (typ, 5V out)  
Wide input voltage range (2.7V to 10V)  
Precision (trimmed) bandgap reference  
Guaranteed specs for -40°C to +125°C  
1µA off-state quiescent current  
The low thermal resistance of the LLP, SOT-223 and T0-252  
packages allow the full operating current to be used even in  
high ambient temperature environments.  
Thermal overload protection  
The use of a PMOS power transistor means that no DC base  
drive current is required to bias it allowing ground pin current  
to remain below 100 µA regardless of load current, input volt-  
age, or operating temperature.  
Foldback current limiting  
T0-252, SOT-223 and 6-Lead LLP packages  
Enable pin (LP38692)  
Dropout Voltage: 450 mV (typ) @ 1A (typ. 5V out).  
Ground Pin Current: 55 µA (typ) at full load.  
Precision Output Voltage: 2.5% (25°C) accuracy.  
Applications  
Hard Disk Drives  
Notebook Computers  
Battery Powered Devices  
Portable Instrumentation
