200mA, Automotive, Ultra-Low  
Quiescent Current, Linear Regulator  
General Description  
Features  
The MAX16910 ultra-low quiescent current, high-voltage  
linear regulator is ideal for use in automotive and battery-  
operated systems. The device operates from a +3.5V to  
+30V input voltage, delivers up to 200mA of load cur-  
rent, and consumes only 20µA of quiescent current at  
no load. The device consumes only 1.6µA current when  
in shutdown. The input is +45V transient tolerant and is  
designed to operate under load-dump conditions. The  
MAX16910 can be configured as either fixed output volt-  
age (+3.3V or +5V) or adjustable output voltage using an  
external resistive divider.  
S Low 20µA Quiescent Current  
S +3.5V to +30V Wide Input Voltage Range, +45V  
Tolerant  
S Operates Through Cold-Crank Conditions  
S Low-Dropout Voltage of 280mV at 200mA  
S Up to 200mA Output Current Capability  
S Stable Operation with Tiny 4.7µF Output Capacitor  
S User-Selectable Output Voltage  
+3.3V or +5V Fixed  
The MAX16910 features an open-drain, active-low RESET  
output with fixed thresholds offered at 92.5% and 87.5%  
of the output voltage. The RESET output remains low for  
a fixed period of 60µs after the output voltage exceeds  
its threshold. The RESET delay can be extended with an  
external capacitor.  
+1.5V to +11V Adjustable with External  
Resistive Divider  
S Open-Drain RESET Output with Adjustable Delay  
S Fixed-Reset Threshold Options: 87.5% or 92.5%  
S High-Voltage Enable Input (+45V)  
The MAX16910 includes an enable input, short-circuit  
protection, and thermal shutdown. The MAX16910 oper-  
ates over the -40°C to +125°C automotive temperature  
range. The device is available in a space-saving, ther-  
mally enhanced, 3mm x 3mm, 8-pin TDFN package and  
5mm x 4mm, 8-pin SO package.
