Voltage Regulators - DC DC Switching Regulators datasheet and documents for LMR36503RFRPER
Voltage Regulators - DC DC Switching Regulators Overview
The LMR36503RFRPER is a synchronous step-down DC/DC converter manufactured by Texas Instruments. It operates within an input voltage range of 3 V to 65 V and delivers a maximum output current of 300 mA. The device features an adjustable output voltage and supports switching frequencies between 400 kHz and 2.2 MHz. Quiescent current is specified at 4 uA. It functions reliably across an operating temperature range from -40°C to +150°C. The component utilizes a VQFN-HR-9 package for surface mount installation.
Voltage Regulators - DC DC Switching Regulators Feature Summary
- Synchronous buck topology for efficient power conversion
- Wide input voltage capability supporting high-voltage sources
- Ultra-low quiescent current for standby efficiency
- Integrated shutdown control for power management
Voltage Regulators - DC DC Switching Regulators Applications
- Industrial automation systems
- Automotive electronics
- Point-of-load regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes
Verify the specific suffix RFRPER to confirm the adjustable output configuration and tape-and-reel packaging format. Ensure compatibility with VQFN-HR-9 footprint requirements during PCB layout. Confirm moisture sensitivity level handling procedures are followed according to datasheet guidelines before assembly.
Voltage Regulators - DC DC Switching Regulators Selection Notes
Select this model when an adjustable output voltage is required alongside wide input range support. Compare against fixed-output variants like LMR36503R5RPER if a standard 5 V rail is sufficient. Consider the 300 mA current limit for load requirements and verify thermal performance within the VQFN-HR-9 package constraints.
Voltage Regulators - DC DC Switching Regulators Part Context
This component belongs to the LMR36503 series of ultra-small synchronous buck converters. It shares architectural similarities with other members such as LMR36503RS3QRPERQ1, though automotive qualification differs. The series emphasizes compact form factors and high efficiency for space-constrained applications requiring robust voltage regulation.
Voltage Regulators - DC DC Switching Regulators Replacement Considerations
LMR36503R5RPER offers a fixed 5 V output instead of adjustable. LMR36503RS3QRPERQ1 provides automotive-grade qualification with similar electrical characteristics.
