1. Overview
1.1 Description
The voltage regulators are designed as fixed-voltage regulator for a wide variety of applications
Including local,on-card regulation. Although designed primarily as a fixed voltage regulator,
these devices can be used with external components to obtain adjustable voltages and currents
1.2 Features
• Output current in excess of 1.0A
• No external components required
• Output voltages (5V, 6V, 8V, 9V, 10V, 12V, 15V, 18V, 24V)
• Internal Thermal shutdown and SOA protection
• Output voltage offered in 4% Tolerance
• Pb-Free Packages are available
• High ESD Level (HBM>8,000V, MM>800V)
1.3 Standard Application

The input voltage must remain typically 2.0V above the output voltage even during the
low point on the ripple voltage.
• C
I is required if regulator is located an appreciable distance from power filter.
• Co improves transient response. Value of 0.1ผ could cause instability.
