3-Terminal Positive Voltage Regulator
Description
3-Terminal Positive Voltage Regulator
DEC.
2009
Product Description
The GS78Lxx Series of positive voltage regulators are inexpensive, easy-to-use devices suitable for a multitude of applications that require a regulated supply of up to 100mA.
Like their higher-powered GS78xx Series cousins, these regulators feature internal current limiting and thermal shutdown making them remarkably rugged.
No external components are required with the GS78Lxx devices in many applications.
These devices offer a substantial performance advantage over the traditional zener diode-resistor combination, as output impedance and quiescent current are substantially reduced.
Features
Wide Range of Available, Fixed Output Voltages Internal Short Circuit Current Limiting Internal Thermal Overload Protection No External Components Required Complementary Negative Regulators Offered (GS79Lxx Series) Available in ±5% Accuracy RoHS and Halogen Free Compliant and 100% Lead(Pb)-Free
Applications
Battery Powered Systems Portable Consumer Equipment Portable Computer Radio Control Systems Logic Systems Power Adapter
