SA1117B
800 mA LDO VOLTAGE REGULATOR
DESCRIPTION
The SA1117B is a positive low voltage dropout regulator; voltage
dropout is only 1.2V at 800mA.
SA1117B provides two versions: fixed and adjustable versions.
VOUT has a tolerance of less than 1.5% for fixed versions 1.5V,
1.8V, 2.5V, 3.3V, 5.0V and adjustable version or 2% output
accuracy for fixed version 1.2V.
The SA1117B offers some key features include thermal shutdown
and current limiting. It is suitable for all electronic products.

SA1117B
FUNCTION DESCRIPTION
The SA1117B is a LDO regulator, it’s pass transistor is made up of a single NPN transistor being driven by a
PNP. The dropout voltage is defined as: VDROP = VBE+ VSAT.
The SA1117B series of fixed and adjustable regulators are easy to use. Output voltages are 1.2V, 1.5V, 1.8V,
2.5V, 3.3V, and 5.0V.On-chip thermal shut down provides protection against any combination of overload and
ambient temperature that would create excessive junction temperature.
The SA1117B requires an output capacitor for device stability. Its value of 22µF tantalum covers all cases of
bypassing the adjustment terminal. Without bypassing the adjustment terminal smaller capacitors can be used
with equally good results which depend upon the application circuit. In general, linear regulator stability
decreases with higher output currents.
