Detailed Description for RP173K331B-TR
Product Overview
The RP173K331B-TR from Nisshinbo Micro Devices Inc. is a linear voltage regulator IC in the RP173x series that provides a positive fixed 3.3 V output from a single regulator channel. It is intended for low-current regulation in surface-mount designs using a 4-UDFN exposed pad package, also identified as DFN(PL)1010-4. The device accepts an input voltage up to 11 V and delivers up to 150 mA, with a maximum dropout of 1.05 V at 150 mA. Its quiescent current is 3.7 µA, and it includes an enable control feature along with over-current and reverse-current protection. The operating temperature range is -40°C to 85°C (TA).
Key Features
- Positive fixed 3.3 V output from a single linear regulator channel.
- Output current capability of 150 mA with maximum dropout of 1.05 V at 150 mA.
- Input voltage rating up to 11 V for single-output regulation.
- Low quiescent current of 3.7 µA.
- Enable control feature for regulator operation management.
- Protection against over-current and reverse-current conditions.
- Surface-mount 4-UDFN exposed pad package, DFN(PL)1010-4.
- Operating temperature range of -40°C to 85°C (TA).
Applications
- Low-current 3.3 V supply rails for compact electronic assemblies.
- Enable-controlled 3.3 V output for simple on/off power management in electronic circuits.
- Regulated power for space-constrained surface-mount boards using a small linear regulator footprint.
Design & Procurement Notes
Designers should verify that the input voltage remains within the 11 V maximum and that the required load current does not exceed 150 mA. Because the dropout specification is 1.05 V at 150 mA, headroom between input and output should be considered for reliable regulation. The enable feature and over-current/reverse-current protection can support basic power management, but layout should account for the 4-UDFN exposed pad package and thermal conditions within the -40°C to 85°C operating range. For procurement, confirm the footprint and land pattern against the DFN(PL)1010-4 package designation.
