RH1185AMK

Negative Regulator with

Adjustable Current Limit

DESCRIPTION

ABSOLUTE MAXIMUM RATINGS

(Note 1)

The RH1185AMK is a 3A low dropout regulator with ad-

justable current limit and remote sense capability. It can

be used as a positive regulator with ﬂoating input or as

a standard negative regulator with grounded input. The

output voltage range is 2.5V to 25V, with 1ꢀ accuracy

on the internal reference voltage.

Input Voltage.............................................................35V

Input-Output Differential ...........................................30V

FB Voltage...................................................................7V

REF Voltage.................................................................7V

Output Voltage ..........................................................30V

Output Reverse Voltage...............................................2V

Operating Ambient Temperature Range.. –55°C to 125°C

Operating Junction Temperature Range

Control Section.................................. –55°C to 150°C

Power Transistor Section ................... –55°C to 175°C

Storage Temperature Range................... –65°C to 150°C

die area. High efﬁciency is maintained by using special

anti-saturation circuitry that adjusts base drive to track

load current.

The on-resistance is typically 0.25Ω. Accurate current

limit is programmed with a single 1/8W external resistor,

with a range of zero to three amperes. A second, ﬁxed

internal limit circuit prevents destructive currents if the

programming current is accidentally overranged.

TO-3 Control Area.............................................1°C/W

Power Transistor...............................................3°C/W

Lead Temperature (Soldering, 10 sec) .................. 300°C

shutdown.
