- 300mA output current capability in a miniature 5-pin SOT-23 package optimized for space-constrained portable and wearable designs
- Wide input voltage range of 2.1V to 6V (absolute max 6.5V) supporting diverse power source types from coin cells to USB and LiPo batteries
- Tape-and-reel packaging (T/R suffix) enabling automated PCB assembly in high-volume consumer electronics manufacturing
Applications
The PTPS7A2018PDBVR is ideal for powering 1.8V digital logic, microcontrollers, and wireless SoCs in battery-operated IoT devices, wearables, and portable medical equipment where board space and efficiency are at a premium. Its low 240mV dropout allows it to be powered directly from a single-cell Li-Ion battery (3.0V–4.2V) or a 3.3V rail without wasting excess headroom. It is also used in post-regulation stages within USB-powered accessories, smart sensors, and industrial handheld devices requiring a clean, stable 1.8V supply.

Frequently Asked Questions
What output voltage and current does the PTPS7A2018PDBVR provide?
The PTPS7A2018PDBVR provides a fixed 1.8V regulated output voltage with a maximum output current of 300mA. It has a maximum dropout voltage of 240mV, meaning it can regulate 1.8V from inputs as low as 2.04V under load, making it well-suited for low-voltage battery-powered applications.
What is the input voltage range of the PTPS7A2018PDBVR?
The PTPS7A2018PDBVR accepts input voltages from 2.1V minimum to 6V maximum, with an absolute maximum rating of 6.5V. This wide range covers single-cell Li-Ion batteries (3.0V to 4.2V), 3.3V system rails, 5V USB power, and other common portable power sources used in embedded and IoT designs.
What package does the PTPS7A2018PDBVR use and how large is it?
The PTPS7A2018PDBVR is housed in a 5-pin SOT-23 surface-mount package (JESD-30 code R-PDSO-G5), one of the smallest standard LDO packages available. This compact footprint makes it ideal for space-constrained applications such as wearables, hearing aids, miniature IoT sensors, and mobile accessories where PCB real estate is strictly limited.
Is the PTPS7A2018PDBVR suitable for battery-powered IoT devices?
Yes, the PTPS7A2018PDBVR is an excellent choice for battery-powered IoT devices. Its 2.1V minimum input voltage allows operation deep into a Li-Ion battery's discharge curve, its 240mV low dropout minimizes wasted energy, and its 1.8V output directly powers common 1.8V wireless SoCs and microcontrollers used in Bluetooth Low Energy, Zigbee, and LoRa sensor nodes.
What does the 'PDBVR' suffix mean for the PTPS7A2018PDBVR?
The suffix encodes package and ordering information: 'PDBVR' indicates the SOT-23 (DBV) 5-pin package variant in tape-and-reel (R) format for automated pick-and-place assembly. The 'P' prefix in the full MPN denotes it is part of Texas Instruments' automotive-grade or prototype product designation depending on context, with the T/R suffix confirming it is supplied in continuous tape-and-reel reels for high-volume SMT production.
