Key Features
- 1 A output current with only 300 mV typical dropout voltage at full load, enabling efficient 5 V to 3.3 V regulation with minimal power loss
- Ultra-low line regulation of 0.002% maximum ensuring stable output across input voltage swings from 3.8 V to 5.5 V
- Compact 5-pin SOT-23 package with fixed output for simplified design and reduced BOM in space-constrained IoT and wearable devices
Applications
The PTLV75733PDBVR is suited for powering microcontrollers, wireless transceivers, and sensors in battery-operated IoT nodes and wearable electronics where minimizing quiescent current extends battery run time. Its 1 A output capacity and low 300 mV dropout allow a single-cell LiPo battery at 3.8 V to maintain a regulated 3.3 V rail even at near-end-of-charge, maximizing usable battery capacity.

Frequently Asked Questions
What is the dropout voltage of PTLV75733PDBVR at 1 A output, and why does it matter for single-cell LiPo designs?
The PTLV75733PDBVR has a typical dropout voltage of 300 mV and a maximum of 475 mV at 1 A output; for a single-cell LiPo battery with a 3.6 V end-of-discharge, the LDO can maintain a regulated 3.3 V rail down to approximately 3.775 V input, extending usable battery life compared to regulators with 600 mV or higher dropout.
How does the 0.002% line regulation of PTLV75733PDBVR benefit a mixed-signal sensor circuit?
With line regulation of only 0.002% maximum, a 1 V swing on the 5.5 V input causes less than 0.1 mV output variation, making the PTLV75733PDBVR suitable for ADC reference and sensor supply rails where input noise from USB VBUS fluctuations would otherwise introduce measurement errors.
Can PTLV75733PDBVR supply a 1 A load from a 5 V USB source while powering a 3.3 V microcontroller subsystem?
Yes, the PTLV75733PDBVR accepts up to 5.5 V input and delivers a fixed 3.3 V output at up to 1 A, comfortably powering a 3.3 V MCU subsystem drawing 200-500 mA from a 5 V USB source; the worst-case power dissipation of approximately (5 V − 3.3 V) × 1 A = 1.7 W must be evaluated against the SOT-23 package thermal resistance.
Is PTLV75733PDBVR a qualified automotive-grade component, and what certifications does it carry?
The PTLV75733PDBVR is a space-level qualified (PT-prefix) radiation-hardened variant intended for aerospace applications, not standard automotive AEC-Q100 Grade 1; designers targeting automotive systems should evaluate the standard TLV75733P which is available in the same 5-pin SOT-23 package without the radiation hardening premium.
