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

characteristicsofaFETpasselementwithsignificantlyless  
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
