Description :
This Series of Fixed-Voltage Monolithic Integrated-Circuit Voltage Regulator is Designed for a wide range of
Applications, which 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 deliverupto 100mA of Output Cuurent. The Internal limiting
and Thermal Shutdown features of these Regulators make them essentially immune to overload. Current
Limiting is included to limit the Peak Output Current (250mA ~ 300mA) to a safe value. .
When used as replacement for a Zener Diode-Resistor Combination, an effective improvement in Output
Impedence obtained together with Lower-Bias Current.

Notes :
1). Pulse Testing Techniques are used to Maintain the Junction Temperature as close to the Ambient Temperature
as Possible. Thermal Effects must be taken into account seperately. All Characteristics are measured with
a 0.33µF Capacitor across the Input and a 0.1µF Capacitor across the Output.
2). The Specification applies only for DC Power Dissipation permitted by Absolute Maximum Ratings.

Note : Bypass Capacitors are Recommended for Optimum Stability and Transient Response and should be
located as close as possible to the Regulators.
