BEIJING ESTEK ELECTRONICS CO.,LTD

This series of fixed-voltage monolithic integrated-circuit voltage regulators is designed for a wide range of applications. These

applications include on-card regulation for elimination of noise and distribution problems associated with single-point regulation. In

addition, they can be used with power-pass elements to make high-current voltage regulators. Each of these regulators can deliver up to

100 mA of output current. The internal limiting and termal shutdown features of these regulators make them essentially immune to

overload. When used as a replacement for a Zener diode-resistor combination, an effective improvement in output impedance can be

obtained together with lower-bias current.

• 3-Terminal Regulators

• Output Current Up to 100 mA

• No External Components

• Internal Thermal Overload Protection

• Internal Short-Circuit Limiting
