Maximum output current: 600mA
Low dropout voltage:
360mV@IOUT=600mA, VOUT=3.3V
Build-in chip enable and discharge circuit
Input voltage range: 1.5~6V
Adjustable output from 0.8V to 5.0V
Output voltage accuracy: ±2%
Output current limit
BL8079AG can provide output value adjustable
from 0.8V to 5.0V.

BL8079AG includes high accuracy voltage
reference, error amplifier, current limit circuit and
output driver module with discharge capability.
BL8079AG has excellent load and line transient
response and good temperature characteristics,
which can assure the stability of chip and power
system. It uses trimming technique to guarantee
output voltage accuracy within ±2%. And it also
provides fold back short-circuit protection,
thermal shutdown and output current limit
function.
Short circuit protection
Over temperature protection
