TPS745-Q1
SBVS355B – JUNE 2019 – REVISED JANUARY 2021  
TPS745-Q1 500-mA LDO With Power-Good in Small Wettable Flank WSON Packages  
1 Features  
3 Description  
AEC-Q100 qualified for automotive applications:  
Temperature grade 1: –40°C to +125°C, TA  
Device junction temperature: –40°C to 150°C  
Package:  
– 2-mm × 2-mm wettable flank WSON  
– 3-mm × 3-mm wettable flank WSON  
Input voltage range: 1.5 V to 6.0 V  
Output voltage range:  
– Fixed option: 0.65 V to 5.0 V  
– Adjustable option: 0.55 V to 5.5 V  
High PSRR: 45 dB at 100 kHz  
Output accuracy: ±0.85% (25°C), ±1.5% maximum  
Power-good output options:  
The TPS745-Q1 is a 500-mA ultra-low-dropout  
regulator (LDO) with power-good functionality. This  
device is available in a small 6-pin, 2-mm × 2-mm and  
a small 8-pin, 3-mm × 3-mm WSON package with  
wettable flanks to facilitate optical inspection. The  
TPS745-Q1 consumes low quiescent current and  
provides fast line and load transient performance.  
The TPS745-Q1 is a flexible device for post-regulation  
by supporting an input voltage range from 1.5 V to  
6.0 V and an externally adjustable output range of  
0.55 V to 5.5 V. The device also features fixed output  
voltages for powering common voltage rails.  
The TPS745-Q1 has a power-good (PG) output that  
monitors 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  
supplies in the system.  
– Open-drain and push-pull  
Ultra-low dropout:  
– 160 mV (max) at 500 mA (3.3 VOUT  
Stable with a 1-µF or larger capacitor  
)
The TPS745-Q1 is stable with small ceramic output  
capacitors, allowing for a small overall solution size. A  
precision band-gap and error amplifier provides high  
accuracy of ±0.85% (max) at 25°C and ±1.5% (max)  
over temperature. This device includes integrated  
thermal shutdown, current limit, and undervoltage  
lockout (UVLO) features. The TPS745-Q1 has an  
internal foldback current limit that helps reduce the  
thermal dissipation during short-circuit events.  
Low IQ: 25 µA (typical), 1.5 µA (shutdown)  
Active output discharge  
Low thermal resistance:  
– DRV (6-pin WSON), RθJA = 80.3°C/W  
– DRB (8-pin WSON), RθJA = 62.0°C/W  
2 Applications
