FEATURES
DESCRIPTION:
The MHL127A Series is a wide-input range, dual linear regulator designed for military and space flight applications.
Packaged in a hermetic, 8-Pin package, the MHL127 provides ±1.0A of output current over the full input voltage range
of +4.25V to +35V, -3.25V to -25V. The device also features internal thermal shutdown and output current-limiting
circuitry. The MHL127A Series is intended for general purpose Op-Amps and Log-Amps with dual supply rails. This
dual linear regulator makes an excellent choice for applications requiring high radiation tolerance & low noise.
The MHL127A Series is provided in adjustable output voltage configuration. Only two resistors are required to
program the output voltage.
