Three Terminal, Precision Adjustable
Positive Voltage Regulator In TO-257 Package
8 09 R0
(COTS) COMMERCIAL OFF-THE-SHELF 1.5 AMP POSITIVE
ADJUSTABLE VOLTAGE REGULATOR, HIGH VOLTA G E
FEATURES
• High Voltage / 60 V o lt
• Built In Thermal Overload Protection
• Short Circuit Current Limiting
DESCRIPTION
These three terminal positive regulators are supplied in hermetically sealed packages.
All protective features are designed into the circuit, including thermal shutdown, current-limiting, and safe-area control. W ith heat sinking, these devices can deliver up to
1.5 amps of output current. The unit also features output voltages that can be fixed
from 1.2 volts to 57 volts using external resistors.

Notes:
1. Load and Line Regulation are specified at a constant junction temperature. Pulse testing with low duty cycle is used.
Changes in output voltage due to heating effects must be taken into account separately.
2. If not tested, shall be guaranteed to the specified limits.
3. The • denotes the specifications which apply over the full operating temperature range.
