OM7800IH Series

ISOLATED HERMETIC TO-257AA FIXED

VOLTAGE REGULATORS

Three Terminal, Fixed Voltage, 1.5 Amp

Precision Positive Regulators In Hermetic

JEDEC TO-257AA Package

FEATURES

• Isolated Hermetic Package, JEDEC TO-257AA Outline

• Output Voltages: 5V, 12V, 15V (Other Voltages Available)

• Output Voltages Set Internally To ±1% or ±2%

• Built-In Thermal Overload Protection

• Short Ciruit Current Limiting

• Product Is Available Screened To OM803

DESCRIPTION

These three terminal positive regulators are supplied in a hermetically sealed

metal package whose outline is similar to the industry standard TO-220 plastic package.

All protective features are designed into the circuit including thermal shutdown, current

limiting and safe-area control. With heat sinking, they can deliver over 1.5 amps of output

current. These units feature internally trimmed output voltages to ±1% or ±2% of nominal

voltage. Standard voltages are 5V, 12V, and 15V. However, other voltages are available

up to 24 volts. These units are ideally suited for Military applications where a hermetically

sealed package is required.

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. Short Circuit protection is only assured up to V_IN= 35V.

3. If not tested, shall be guaranteed to the specified limits.

The • denotes the specifications which apply over the full operating temperature range.
