LP38691-ADJ/LP38693-ADJ  
500mA Low Dropout CMOS Linear Regulators with  
Adjustable Output  
Stable with Ceramic Output Capacitors  
General Description  
The LP38691/3-ADJ low dropout CMOS linear regulators  
provide 2.0% precision reference voltage, extremely low  
Features  
n Output voltage range of 1.25V - 9V  
n 2.0% adjust pin voltage accuracy (25˚C)  
@
dropout voltage (250mV 500mA load current, VOUT = 5V)  
@
n Low dropout voltage: 250mV 500mA (typ, 5V out)  
and excellent AC performance utilizing ultra low ESR ce-  
ramic output capacitors.  
n Wide input voltage range (2.7V to 10V)  
n Precision (trimmed) bandgap reference  
n Guaranteed specs for -40˚C to +125˚C  
n 1µA off-state quiescent current  
n Thermal overload protection  
The low thermal resistance of the LLP and SOT-223 pack-  
ages allow the full operating current to be used even in high  
ambient temperature environments.  
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  
voltage, or operating temperature.  
n Foldback current limiting  
n SOT-223 and 6-Lead LLP packages  
n Enable pin (LP38693-ADJ)  
@
Dropout Voltage: 250 mV (typ) 500mA (typ. 5V out).  
Applications  
Ground Pin Current: 55 µA (typ) at full load.  
Adjust Pin Voltage: 2.0% (25˚C) accuracy.  
n Hard Disk Drives  
n Notebook Computers  
n Battery Powered Devices  
n Portable Instrumentation  
Typical Application Circuits  
20126801  
20126802  
VOUT = VADJ x (1 + R1/R2)  
Note: *Minimum value required for stability.
