Automotive 300mA LDO Voltage Regulators  
with Tracker Output and Overvoltage Protector  
8/MAX510  
General Description  
Features  
The MAX15008 features a 300mA LDO regulator, a volt-  
age tracker, and an overvoltage protection (OVP) con-  
troller to protect downstream circuits from high-voltage  
load dump. The MAX15010 includes only the 300mA  
LDO voltage regulator and voltage tracker. Both devices  
operate over a wide 5V to 40V supply voltage range and  
are able to withstand load-dump transients up to 45V. The  
MAX15008/MAX15010 feature short-circuit and thermal-  
shutdown protection. These devices offer highly integrat-  
ed power-management solutions for automotive  
applications such as instrument clusters, climate control,  
and a variety of automotive power-supply circuits.  
♦ 300mA LDO Regulator, Voltage Tracker, and OVP  
Controller (MAX15008)  
♦ 300mA LDO Regulator and Voltage Tracker  
(MAX15010)  
♦ 50mA Voltage Tracker with 3mV Tracking Accuracꢀ  
♦ 5V to 40V Wide Operating Supplꢀ Voltage Range  
♦ 45V Load Dump Protection  
♦ 70µA Quiescent Current LDO Regulator  
♦ OVP Controller Disconnects or Limits Output from  
Batterꢀ Overvoltage Conditions (MAX15008)  
♦ LDO Regulator with Enable, Hold, and Reset  
The 300mA LDO regulator consumes less than 70µA qui-  
escent current at light loads and is well suited to power  
always-on circuits during “key off” conditions. The LDO  
features independent enable and hold inputs as well as a  
microprocessor (µP) reset output with an adjustable reset  
timeout period.

The voltage tracker accurately ( 3mV) tracks a voltage  
applied to its input from either the LDO output or an exter-  
nal source. It can supply up to 50mA of current to a  
remote sensor, allowing for precise ratiometric tracking in  
automotive applications. A separate enable input turns  
the tracker on or off, reducing supply current when the  
tracker is unused. The voltage tracker also features pro-  
tection against battery reversal, an output short circuit to  
the battery, or an output-voltage excursion below ground  
potential to as much as -5V.

The MAX15008 OVP controller operates with an external  
enhancement mode n-channel MOSFET. While the moni-  
tored voltage remains below the adjustable threshold, the  
MOSFET stays on. When the monitored voltage exceeds  
the OVP threshold, the OVP controller quickly turns off the  
external MOSFET. The OVP controller is configurable as a  
load-disconnect switch or a voltage limiter.
