1.1

FEATURES

• Approved To DE S C Standardized Military Drawings

• Low Dropout Voltage, 0.6 V @ IO= 1 A

• Output Current in Excess of 1 A [LCC 20 (N2) package limited to 0.3A]

• Reverse Battery Protection

• Internal Short Circuit Protection

• Isolated and Non-Isolated Hermetic Package Types

• Output Voltages: - 5V, -5.2V, -12V, & -15V

DESCRIPTION

The OM2990 series of fixed voltage regulators are designed to provide up to 1.5A with
high ef ficiency . It has the ability to source 1A of output current with a typical dropout
voltage of 0.6V and a maximum of 1V over the entire operating temperature range. It is
supplied in hermetic packages and is ideally suited for all applications where small size
and high reliability are required.
