1 Version: H1607

1A Low Dropout Positive Voltage Regulator

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.

FEATURES

● Low Dropout Performance 1.5V max.

● Fast Transient Response

● Built-in thermal shutdown

● Output Current Limit

● Line Regulation Typical 0.2%

● Load Regulation Typical 0.05%

● Low-ESR Ceramic Capacitor (MLCC) required for

Stability.

● Good Ripple Rejection

● Compliant to RoHS Directive 2011/65/EU and

WEEE 2002/96/EC

● Halogen-free according to IEC 61249-2-21

APPLICATION

● PC peripheral

● Communication

● Consumer equipment
