DESC APPROVED LOW DROPOUT NEGATIVE
Three Terminal, Fixed Voltage,
Low Dropout Negative Voltage Regulator
In Hermetic Packages
FEATURES
• Approved To DE S C Standardized Military Drawings
• Low Dropout Voltage, 0.6 V @ I
O = 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 efficiency.
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.
