GM7900 Series 1.5A NEGATIVE VOLTAGE REGULATOR Description Features The GM7900 series of fixed-negative voltage monolithic integrated circuit voltage regulators is designed to complement Series GM7800 in a wide range of applications. These applications include on-card regulation for elimination of noise and distribution problems associated with single-point regulation. Each of these regulators can deliver up to 1.5A of output current. The internal limiting and thermal shutdown features of these regulators make them essentially immune to overload. In addition to use as fixed-voltage regulators, these devices can be used with external components to obtain adjustable output voltages and current and also as the power pass element in precision regulators. Output current up to 1.5A Available Output Voltage Options from 5V to -24V 3- Terminal Regulators Internal Thermal Overload Protection Internal Short-Circuit Current Limiting Output Transistor Safe-Area Protection TO-220, TO-252 and TO-263 Packages High Power Dissipation Capability The GM7900 series are available in TO-220, TO252, TO-263 packages. Typical Application Circuit VIN VOUT 1.5A GM7900 CIN 2µF COUT 1µF COUT 2 0.1µF GM7900V2.00 When using a negative regulator, bypass capacitors are a must on both input and output. Recommended values are 2µF on the input and 1µF on the output. It is considered good practice to include a 0.1µF capacitor on the output to improve the transient response. These capacitors may mylar, ceramic, or tantalum, provided that they have good high frequency characteristics www.gammamicro.com.tw 1 GM7900 Series 1.5A NEGATIVE VOLTAGE REGULATOR Marking Information and Pin Configurations (Top View) – Green Products TO 252 (D-PAK) TO 220 GM79VVG AYWW TO 263 (D2-PAK) GM79VVG AYWW GM79VVG AYWW GM7900V2.00 3.
