A8450  
Automotive Multioutput Voltage Regulator  
Features and Benefits  
6 V to 45 V input range  
Description  
The A8450 is a multioutput power supply intended for  
DC-to-DC buck converter with 5.7 V output  
Overcurrent protection with foldback, and undervoltage  
lockout (UVLO)  
automotive applications. The A8450 operates from a wide  
input supply range and is designed to satisfy the requirements  
of high ambient temperature environments.  
Dual 5 V outputs  
Four regulated voltage outputs provide multiple options. The  
3.3 Vregulator and the 1.2 to 3.3Vadjustable regulator can be  
usedtopowermicrocontrollerorDSPcores,orforI/O,sensing,  
and A-to-D conversion. Two 5 V outputs, one digital and the  
other analog, feature output tracking within 0.5% of each other  
over the operating temperature range. In addition, the analog  
regulator is protected against short-to-battery conditions. All  
four regulators feature foldback current limit protection.  
Digital 5 V ±2%, 200 mA  
Analog 5 V, 200 mA  
Short-to-supply protection on analog regulator  
Analog to digital regulator output tracking <0.5%  
throughout operating temperature range  
Continued on the next page…  
The device can be enabled or disabled using two input pins.  
The high voltage input, on the ENBAT pin, allows enable/  
disable using an engine ignition or battery switch signal. The  
logic-level input, on the ENB pin, allows enable/disable by  
microcontroller or DSP signals.  
Package: 24 pin SOIC (suffix LB)  
When disabled, the A8450 draws less than 10 μA of current.  
A POR (power-on-reset) block monitors the supply voltages  
and provides a reset signal, with an adjustable delay, for
