Product details

Overview

RP118N201B-TR-FE from Ricoh Electronic Devices is a 2.0 V output, 100 mA ultra-low quiescent current LDO voltage regulator in SOT-23-5 package. It delivers ±0.8% output accuracy, 0.15 V typical dropout at 100 mA, and 0.2 µA supply current - enabling multi-year battery life in wearable sensors and BLE peripherals powered by coin cells or Li-ion batteries.

For engineers reviewing the RP118N201B-TR-FE datasheet, RP118N201B-TR-FE pinout, RP118N201B-TR-FE application, or RP118N201B-TR-FE equivalent, key selection criteria include ultra-low I_SS, auto-switching between fast-response and low-power operating modes, CE pin control with active-high enable, and guaranteed stability with ≥1.0 µF ceramic output capacitance.

Technical Context

The RP118N201B-TR-FE implements dual-mode operation: automatically shifting between fast-response mode (for load transients ≥1.5 mA) and ultra-low-power mode (for loads ≤0.08 mA). Its internal architecture includes a bandgap reference, error amplifier, PMOS pass transistor, and fold-back current limit (50 mA short-circuit protection).

It operates across 1.7–5.5 V input range with 2.0 V fixed output, supports 100 mA continuous output, and maintains regulation down to 0.15 V dropout. The CE pin enables full shutdown with 0.002 µA standby current, and the device requires no external compensation when using ≥1.0 µF ceramic capacitors on both input and output.

Key Specifications

Parameter	Value and Actual Design Meaning

Supply Current (I_SS)	Typ. 0.2 µA - extends coin-cell lifetime beyond 10 years in always-on IoT endpoints.
Standby Current	Typ. 0.002 µA - enables near-zero power consumption during deep-sleep states.
Dropout Voltage	Typ. 0.15 V at 100 mA - allows operation down to 2.15 V input, compatible with single-cell Li-ion (2.5–4.2 V) and alkaline/coin cells.
Input Voltage Range	1.7 V to 5.5 V (6.5 V abs max) - supports wide battery chemistries and upstream DC-DC stages.
Output Accuracy	±0.8% over −40°C to +85°C - meets tight tolerance requirements for precision analog sensor interfaces.
Short-Circuit Protection	Fold-back limit typ. 50 mA - prevents thermal runaway while sustaining regulated output during fault conditions.

SOT-23-5 package (2.9 mm × 1.6 mm × 1.1 mm), thermally enhanced with GND-connected tab. Compatible with standard JEDEC STD. 51-7 land pattern and reflow profiles.

Pin/Terminal	Circuit Role	Design Meaning
1 - VDD	Input power supply	Accepts 1.7–5.5 V; requires ≥1.0 µF ceramic decoupling capacitor placed adjacent to pin.
2 - GND	Ground reference	Primary ground return; electrically connected to exposed thermal pad - must be soldered to PCB ground plane.
3 - CE	Chip enable control	Active-high logic input; drives device into 0.002 µA standby when pulled low; open-circuit not allowed.
4 - NC	No connection	Internally unconnected; must remain floating - no trace or via permitted.
5 - VOUT	Regulated output	Delivers 2.0 V ±0.8%; requires ≥1.0 µF ceramic capacitor directly between this pin and GND.

Key Features

Feature	Design Value
Ultra-low quiescent current	0.2 µA typ. - enables >10-year operation on CR2032 (225 mAh) at 1 µA average system load.
Auto-switching dual-mode operation	Seamlessly transitions between fast-response (≥1.5 mA load) and ultra-low-power (≤0.08 mA) modes - eliminates manual mode selection.
Stable with ceramic capacitors only	Guaranteed stability using ≥1.0 µF X5R/X7R ceramics on input and output - no ESR requirements or tantalum alternatives needed.
Integrated fold-back protection	50 mA short-circuit current limit - protects IC and PCB traces without external current-sense circuitry.
Wide input voltage range	1.7–5.5 V operation - supports direct connection to partially discharged Li-ion (2.5 V), alkaline (1.8 V), or coin cells (3.0 V).

Alternative Part	Technical Difference	Application Difference	Selection Advice
Torex XC6210B202MR-G	2.0 V fixed, 100 mA, 0.6 µA I_SS, SOT-25 - higher quiescent current, same package.	Lacks auto-switching mode; requires external resistor for EN threshold adjustment.	Select when cost sensitivity outweighs battery life; verify EN logic compatibility.
Microchip MCP1703T-2002E/MB	2.0 V fixed, 250 mA, 1.8 µA I_SS, SOT-23-5 - higher I_SS, higher current capability.	Designed for general-purpose low-noise use; no fast-response/low-power auto-switching.	Select when >100 mA load margin is required and 1.8 µA I_SS is acceptable for target battery life.

Compared with XC6210B202MR-G and MCP1703T-2002E/MB, RP118N201B-TR-FE provides the lowest supply current (0.2 µA vs. 0.6 µA/1.8 µA) and unique automatic dual-mode operation - critical for multi-year coin-cell deployments where every nanoamp matters.

FAQ

What is the minimum input voltage required for regulation at 2.0 V output?

The RP118N201B-TR-FE maintains regulation down to 2.15 V input (2.0 V + 0.15 V dropout) at 100 mA load. At lighter loads, dropout decreases - e.g., 0.05 V at 10 mA - enabling operation from as low as 2.05 V input. Absolute minimum input is 1.7 V, but regulation is not guaranteed below dropout threshold.

Can the CE pin be left floating during operation?

No. The CE pin has no internal pull-up or pull-down; leaving it floating causes undefined behavior and may increase supply current due to through-current in internal logic gates. It must be actively driven high (≥1.0 V) for operation or low (≤0.4 V) for shutdown - a pull-up resistor to VDD is acceptable if system timing permits.

Is an input capacitor mandatory, and what value is recommended?

Yes. A minimum 1.0 µF ceramic capacitor (X5R/X7R, 0402 or larger) is required between VDD and GND, placed as close as possible to pins 1 and 2. This suppresses high-frequency noise from upstream sources and prevents instability caused by trace inductance - omitting it risks oscillation or erratic enable/disable behavior.

Does the RP118N201B-TR-FE support auto-discharge functionality?

No. The "B" suffix in RP118N201B-TR-FE indicates active-high CE with auto-discharge disabled. When CE is pulled low, output is disabled but VOUT remains floating (no internal discharge path). For auto-discharge, select the "D" variant (e.g., RP118N201D-TR-FE), which adds an NMOS discharge switch between VOUT and GND.
