MAX16910
200mA, Automotive, Ultra-Low
Quiescent Current, Linear Regulator
General Description
Benefits and Features
● Enables System Designers to Meet Stringent Module
Requirements for 100μA Quiescent Current
• Low 20µA Quiescent Current
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
current, 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.
• Up to 200mA Output-Current Capability
• User-Selectable Output Voltage (+3.3V or +5V
Fixed and +1.5V to +11V Adjustable with
External Resistive Divider)
● Tiny Output Capacitors Reduce Board Space and
BOM Cost
• Stable Operation with 4.7µF Output Capacitor
● Accurate RESET Output with Adjustable Delay
Eliminates Need for Separate Reset IC
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.
• Open-Drain RESET Output with Adjustable Delay
• Fixed-Reset Threshold Options: 87.5% or 92.5%
● Operates Through Cold-Crank Conditions
• Low-Dropout Voltage of 280mV at 200mA
• +3.5V to +30V Wide Input Voltage Range,
+45V Tolerant
The MAX16910 includes an enable input, short-
circuit protection, and thermal shutdown. The MAX16910
operates over the -40°C to +125°C automotive tempera-
ture range. The device is available in a space-saving,
thermally enhanced, 3mm x 3mm, 8-pin TDFN package
and 5mm x 4mm, 8-pin SO package.
