Product details

Overview

RP130N151B-TR-YE from Nisshinbo Micro Devices is a low-noise, 150 mA CMOS LDO regulator with fixed 1.5 V output, ±1.0% accuracy (V_OUT > 2.0 V), 80 dB ripple rejection at 1 kHz, 38 µA typical supply current, and active-high chip enable. It operates from 1.7–6.5 V input and delivers stable power to noise-sensitive analog circuits in portable instrumentation and battery-powered microcontrollers.

For engineers reviewing the RP130N151B-TR-YE datasheet, RP130N151B-TR-YE pinout, RP130N151B-TR-YE application, or RP130N151B-TR-YE equivalent, key selection criteria include dropout voltage (0.54 V @ 150 mA), standby current (0.1 µA), temperature drift (±20 ppm/°C), ceramic capacitor compatibility (≥0.47 µF), and SOT-23-5 package thermal performance (θ_ja = 150°C/W).

Technical Context

The RP130N151B-TR-YE implements a CMOS-based error amplifier with built-in voltage reference and resistor network for precise 1.5 V regulation. Its active-high CE pin enables direct interface with logic-level control signals without level-shifting, and its fold-back current limit (40 mA short-circuit) protects against sustained overloads.

Designed for ultra-low quiescent operation, the IC achieves 38 µA supply current via optimized CMOS process and integrates internal phase compensation to ensure stability with ≥0.47 µF ceramic output capacitors-eliminating need for external compensation components across 1 mA–150 mA load range.

Key Specifications

Pinout & Package

SOT-23-5 package with exposed tab connected to GND; compact 2.9 mm × 1.9 mm footprint enables high-density PCB layouts in space-constrained portable electronics.

Pin/Terminal	Circuit Role	Design Meaning
1	VDD	Main input supply pin; accepts 1.7–6.5 V with 7.0 V absolute max rating
2	GND	Power ground reference; internal substrate connection and thermal path via exposed tab
3	CE	Active-high chip enable; pulls to VDD for operation, 0.1 µA standby current when pulled low
4	NC	No internal connection; must be left unconnected or tied to GND per layout best practice
5	VOUT	Regulated 1.5 V output; requires ≥0.47 µF ceramic capacitor placed adjacent to pin for stability

Key Features

Feature	Design Value
Ultra-low supply current	38 µA typ. enables multi-year battery life in coin-cell-powered remote sensors
High ripple rejection	80 dB @ 1 kHz allows clean LDO output even when fed from noisy buck converter outputs
Low dropout voltage	0.54 V @ 150 mA permits use with aging batteries or low-headroom input sources
Ceramic capacitor compatible	Stable with ≥0.47 µF X5R/X7R ceramics - eliminates costly tantalum or electrolytic alternatives
Thermal protection	Built-in junction temperature monitoring prevents damage during sustained overload or poor heatsinking
Auto-discharge support	Not implemented in B-version - CE deactivation leaves VOUT floating; D-version required for fast discharge

Equivalent & Alternatives

The following parts are listed as comparable options for similar LDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AP2112K-1.5TRG1	Higher 65 µA quiescent current; 60 dB ripple rejection; no CE pin	Lacks enable control - unsuitable for duty-cycled systems requiring deep-sleep power gating	Select only if CE functionality is unnecessary and board space allows larger SOT-23-3 footprint
MCP1700T-1502E/TT	3.5 µA IQ; 150 mA rating; active-low CE; ±2% output accuracy	Looser voltage tolerance impacts precision analog stages; lower IQ benefits ultra-long-life applications	Prefer for energy-harvesting or solar-charged systems where 1.5 V accuracy is secondary to ultra-low IQ

Compared with AP2112K-1.5TRG1 and MCP1700T-1502E/TT, RP130N151B-TR-YE uniquely balances 38 µA IQ, 80 dB ripple rejection, ±1.0% accuracy, and active-high CE in SOT-23-5 - making it optimal for battery-powered instrumentation requiring both precision and controllable power states.

FAQ

What is the minimum input voltage required for 1.5 V output at full 150 mA load?

The RP130N151B-TR-YE requires a minimum input voltage of 2.04 V under full load, calculated from its typical dropout voltage of 0.54 V added to the 1.5 V output. This allows operation from partially discharged single-cell Li-ion batteries (down to ~2.1 V) while maintaining regulation and specified accuracy.

Can I use a 1 µF ceramic capacitor instead of the recommended 0.47 µF for C_OUT?

Yes - a 1 µF X5R or X7R ceramic capacitor meets and exceeds the minimum 0.47 µF requirement. Larger values improve transient response and further reduce output impedance, but do not affect stability since the IC is internally compensated for ≥0.47 µF. Avoid high-ESR types like tantalum unless verified with manufacturer's stability guidelines.

Is the exposed tab on the SOT-23-5 package electrically connected?

Yes - the exposed thermal pad (tab) on the bottom of the SOT-23-5 package is internally connected to GND. It serves as both a thermal conduction path and an electrical ground node. For optimal thermal performance and EMI suppression, it should be soldered to a dedicated GND copper pour using multiple thermal vias.

Does the RP130N151B-TR-YE include reverse-polarity protection?

No - the RP130N151B-TR-YE does not integrate reverse-polarity protection. Applying reversed input voltage (VDD < GND) violates Absolute Maximum Ratings and may cause permanent damage. External protection, such as a series Schottky diode or ideal diode controller, must be added if reverse-voltage exposure is possible in the target application.
