Space Saving 800mA Low-Dropout Linear Regulator with Internal Current Limit - LM1117

LM1117 (ACTIVE)

Space Saving 800mA Low-Dropout Linear Regulator with Internal Current Limit

 

Recommended alternative parts

  • TLV757P  -  TLV757P is a lower IQ (25uA), lower voltage (5.5V max) 1 A LDO
  • TLV760  -  TLV760 is a wide input (24V) Low current (150mA) linear regulator
  • LP38798  -  LP38798 is a higher current (1A max), ceramic cap stable LDO

Description

The LM1117 is a low dropout voltage regulator with a dropout of 1.2 V at 800 mA of load current.

The LM1117 is available in an adjustable version, which can set the output voltage from 1.25 to 13.8 V with only two external resistors. In addition, it is available in five fixed voltages, 1.8 V, 2.5 V, 3.3 V, and 5 V.

The LM1117 offers current limiting and thermal shutdown. Its circuit includes a Zener trimmed bandgap reference to assure output voltage accuracy to within ±1%.

A minimum of 10-µF tantalum capacitor is required at the output to improve the transient response and stability.
