TPS7A44
SBVS421 – NOVEMBER 2021
TPS7A44 50-mA, 65-V, Low IQ, Low-Dropout Linear Voltage Regulator
With Power-Good and Selectable Mid-Output Rail
1 Features
3 Description
•
•
Input voltage: 4 V to 65 V
The TPS7A44 low-dropout (LDO) linear voltage
regulator introduces a combination of a 4-V to 65-V
input voltage range with very-low quiescent current.
Wide output (OUT) voltage range:
– Adjustable: 1.24 V to 14.5 V
– Fixed: 1.25 V to 5.0 V
Selectable intermediate output (MID_OUT):
– 10 V, 12 V, 15 V
This device can support a wide range of input
voltages (for example, a 15-s battery and 24-V to
48-V line power) and withstand line transient voltages
up to 85 V. These features help modern applications
meet increasingly stringent energy requirements, and
help extend battery life in portable-power solutions.

Maximum output current:
– 50 mA (shared between OUT and MID_OUT)
1% accuracy over temperature
Ultra-low IQ: 5.5 μA

The TPS7A44 output (OUT) is available in both
fixed and adjustable output versions, which can
regulate from 1.24 V to 14.5 V at 1% accuracy. The
device also provides a second intermediate output
(MID_OUT) that can be set to 10 V, 12 V, and 15 V
using the MVSEL pins and can be used to bias gate
drivers in place of a discrete regulator.
Precision enable
Power-good (PG) output (open drain)
Thermal shutdown and overcurrent protection
Operating junction temperature: –40°C to +125°C
Package: HVSSOP-10 (RθJA = 53.7°C/W)

Cordless power tools
DC motors and fans
The TPS7A44 features a precision enable input that
helps enable or disable the LDO at a fixed and
accurate threshold voltage using a resistor divider
from the input.
Programmable logic controllers (PLCs)
Field transmitter and process sensors
Smoke and heat detectors
EV charging infrastructure
Battery packs
The power-good (PG) output is used to monitor the
voltage at the feedback pin to indicate the status of
the output voltage. The EN input and PG output can
be used for sequencing multiple power sources in the
system.
