TS1117B

1A Low Dropout Positive Voltage Regulator

1/8

Version: F14

TO-252

(DPAK)

SOT-223

SOP-8

General Description

TS1117B are high performance positive voltage regulators are designed for use in applications requiring low

dropout performance at full rated current, Additionally, TS1117B provides excellent regulation over variations due

to changes in line, load and temperature. Outstanding features include low dropout performance at rated current,

fast transient response, internal current limiting and thermal shutdown protection of the output device. TS1117B

are three terminal regulators with fixed and adjustable voltage options available in popular packages.
