LP2954/LP2954A  
5V and Adjustable Micropower Low-Dropout Voltage  
Regulators  
General Description  
Features  
n 5V output within 1.2% over temperature (A grade)  
n Adjustable 1.23 to 29V output voltage available  
(LP2954IM and LP2954AIM)  
The LP2954 is a 5V micropower voltage regulator with very  
low quiescent current (90 µA typical at 1 mA load) and very  
low dropout voltage (typically 60 mV at light loads and  
470 mV at 250 mA load current).  
n Guaranteed 250 mA output current  
n Extremely low quiescent current  
n Low dropout voltage  
The quiescent current increases only slightly at dropout  
(120 µA typical), which prolongs battery life.  
The LP2954 with  
a
fixed 5V output is available in the  
n Reverse battery protection  
three-lead TO-220 and TO-263 packages. The adjustable  
LP2954 is provided in an 8-lead surface mount, small outline  
package. The adjustable version also provides a resistor net-  
work which can be pin strapped to set the output to 5V.  
n Extremely tight line and load regulation  
n Very low temperature coefficient  
n Current and thermal limiting  
n Pin compatible with LM2940 and LM340 (5V version  
only)  
Reverse battery protection is provided.  
The tight line and load regulation (0.04% typical), as well as  
very low output temperature coefficient make the LP2954  
well suited for use as a low-power voltage reference.  
n Adjustable version adds error flag to warn of output drop  
and a logic-controlled shutdown  
Output accuracy is guaranteed at both room temperature  
and over the entire operating temperature range.  
Applications  
n High-efficiency linear regulator  
n Low dropout battery-powered regulator
