What are the key features of PTPS7A2533DRVR?
- Ultra-low quiescent current LDO with 300mA output capability and 0.21V typical dropout voltage extends battery life in always-on and low-standby-power applications
- Integrated power good output provides a system-level supervisory signal for sequencing or fault detection without external voltage monitoring circuits
- Wide 3.8V to 18V input range with 0.0033% maximum line regulation supports diverse supply rails in industrial, automotive, and IoT applications
What is PTPS7A2533DRVR used for?
The PTPS7A2533DRVR is optimized for battery-powered IoT sensors, wearables, and always-on monitoring systems where minimizing quiescent current is critical to extending battery life. Its power good output simplifies power sequencing in multi-rail systems such as microcontroller-based designs where controlled startup order prevents latch-up or brownout faults. The wide 18V input range and low 0.34V maximum dropout voltage also make it suitable for automotive and industrial equipment operating from unregulated or fluctuating supply rails.

Frequently Asked Questions
What is the output current and dropout voltage of the PTPS7A2533DRVR?
The PTPS7A2533DRVR provides up to 300mA output current with a typical dropout voltage of 0.21V and a maximum of 0.34V. This low dropout characteristic allows the regulator to maintain output regulation even when the input supply is only slightly higher than the output voltage, which is critical in battery-powered applications near end-of-discharge.
What is the input voltage range of the PTPS7A2533DRVR?
The PTPS7A2533DRVR accepts input voltages from 3.8V minimum to 18V maximum, with an absolute maximum rating of 20V. This wide range makes it versatile for use with standard 5V, 9V, 12V, and other common supply rails found in consumer electronics, industrial sensors, and automotive power systems.
What is the power good feature and how is it used?
The power good (PG) pin is an open-drain output that goes high when the LDO output voltage reaches its regulation target, and goes low if the output drops out of regulation due to low input voltage or overload. System designers use this signal for power sequencing, microcontroller reset control, or fault indication without needing an external supervisory IC.
What package is the PTPS7A2533DRVR available in?
The PTPS7A2533DRVR is housed in a 6-pin SOT-23 style small outline no-lead package, as indicated by the JESD-30 code S-PDSO-N6 and the 'DRVR' suffix denoting tape-and-reel packaging. This compact surface-mount package is ideal for space-constrained PCB layouts in portable and wearable electronics.
How does the ultra-low quiescent current of the PTPS7A2533DRVR benefit battery-powered designs?
Ultra-low IQ LDOs like the PTPS7A2533DRVR consume minimal current in standby or light-load conditions, which directly reduces self-discharge of the battery when the system is idle. For IoT sensors or wearables that spend most of their time in sleep mode, a lower IQ regulator can extend battery life by weeks or months compared to a standard LDO drawing hundreds of microamps at no load.
