Three Terminal +5V, +12V, +15V, Low Dropout
TO-257/TO-258 Fixed Voltage Regulators
4 11 R2
Supersedes 1 07 R1
7.5A, 5A, 3A, 1.5A LOW DROPOUT
FIXED VOLTAGE POSITIVE REGULATORS
FEATURES
• +5V, +12V, and +15V Output Voltage
• Operates Down to 1V Dropout
• .015% Line Regulation / .01% Load Regulation
• Output Voltage Trimmed to ±1%
• Hermetic TO-257 and TO-258 Isolated Package
DESCRIPTION
These three terminal positive fixed voltage regulators are designed to provide 7.5A,
5A, 3A, and 1.5A with higher efficiency than conventional voltage regulators. The
devices are designed to operate to 1 Volt input to output differential and the dropout
voltage is specified as a function of load current. All devices are pin compatible with
older three terminal regulators. Supplied in the easy-to-use hermetic metal TO-257
and TO-258 JEDEC packages, these devices are ideally suited for Military
applications where small size, hermeticity and high reliability are required.
