Product details
Overview
RP118N201D-TR-FE from Ricoh Electronic Devices is a 2.0 V fixed-output, 100 mA ultra-low quiescent current LDO voltage regulator in SOT-23-5 package. It delivers ±0.8% output accuracy, 0.15 V dropout at 100 mA, and 0.2 µA supply current-enabling multi-year battery life in coin-cell-powered wearables and Bluetooth Low Energy sensor nodes.
For engineers reviewing the RP118N201D-TR-FE datasheet, RP118N201D-TR-FE pinout, RP118N201D-TR-FE application, or RP118N201D-TR-FE equivalent, key selection criteria include its auto-discharge function (D version), thermal performance in SOT-23-5, fast/low-power mode switching thresholds (1.5 mA / 80 µA), and guaranteed stability with ≥1.0 µF ceramic output capacitance.
Technical Context
The RP118N201D-TR-FE implements an automatic dual-mode control architecture that shifts between fast-response mode (for load transients) and ultra-low-power mode (for standby). Its internal fold-back protection limits short-circuit current to 50 mA, and the CE pin is active-high with auto-discharge functionality enabled on the 'D' variant.
It operates across 1.7–5.5 V input range with 2.0 V nominal output, supports −40°C to +85°C ambient operation, and requires no external compensation-achieving stability with 1.0 µF ceramic COUT due to integrated phase compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.0 V ±0.8% (ensures stable MCU core/sensor bias under battery discharge) |
| Supply Current | Typ. 0.2 µA (enables >10-year operation on CR2032 at 1 µA average load) |
| Standby Current | Typ. 0.002 µA (supports deep-sleep states in BLE advertising intervals) |
| Dropout Voltage | Typ. 0.15 V at 100 mA (allows regulation down to 2.15 V input-critical for Li-ion end-of-discharge) |
| Input Voltage Range | 1.7 V to 5.5 V (covers coin cell, single Li-ion, and 3.3 V system rails) |
| Output Accuracy | ±0.8% over −40°C to +85°C (meets tight ADC reference and RF oscillator VDD requirements) |
| Thermal Shutdown | Integrated protection (prevents thermal runaway during sustained 100 mA loads in confined PCB areas) |
Pinout & Package
SOT-23-5 package (2.9 mm × 1.6 mm × 1.1 mm), thermally enhanced with GND-connected tab; JEDEC-compliant land pattern supports 660 mW power dissipation at Ta = 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VDD | Input supply pin | Accepts 1.7–5.5 V; requires ≥1.0 µF ceramic bypass capacitor placed adjacent to pin |
| 2: GND | Ground reference | Connected to exposed thermal tab; must be tied to PCB ground plane for thermal and noise integrity |
| 3: CE | Chip enable input | Active-high logic; enables auto-discharge of VOUT when deasserted (D-version behavior) |
| 4: NC | No connection | Internally unconnected; must remain floating-no routing or stitching allowed |
| 5: VOUT | Regulated output | Delivers 2.0 V ±0.8%; requires ≥1.0 µF ceramic capacitor with low ESR (<100 mΩ) for stability |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply current | 0.2 µA typ. enables decade-scale battery life in always-on IoT endpoints |
| Auto-discharge function | VOUT actively discharges to GND when CE is low-eliminates residual voltage holding up downstream logic |
| Dual operating mode | Automatic transition between fast-response (≥1.5 mA load) and low-power (≤80 µA load) modes without external control |
| Fold-back current limit | 50 mA short-circuit protection prevents thermal damage during board-level fault conditions |
| Ceramic capacitor compatibility | Stable with ≥1.0 µF X5R/X7R ceramics-avoids costly tantalum or polymer capacitors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-IQ LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6210B202MR-G | 0.6 µA IQ, no auto-discharge, same SOT-23-5 package | Lacks VOUT discharge on shutdown-requires external circuitry for clean reset | Select when auto-discharge is unnecessary and lowest possible BOM count is prioritized |
| Ricoh RP118N201B-TR-FE | Same specs except CE pin disables regulator without discharging VOUT (B-version) | Retains VOUT voltage after disable-suitable for systems requiring hold-up or state retention | Select when downstream circuitry must retain bias during CE assertion |
Compared with XC6210B202MR-G and RP118N201B-TR-FE, the RP118N201D-TR-FE uniquely combines 0.2 µA IQ with integrated auto-discharge-reducing system-level complexity in battery-constrained, rapidly cycling IoT nodes.

FAQ
What is the minimum input voltage required for stable 2.0 V output at 100 mA load?
The RP118N201D-TR-FE requires a minimum input voltage of 2.15 V to maintain regulation at 100 mA, based on its typical 0.15 V dropout voltage. Below this threshold, output voltage drops linearly with input-verified across −40°C to +85°C operating range per Electrical Characteristics table.
Does the auto-discharge function work with any output capacitor value?
Auto-discharge operates effectively with output capacitors from 1.0 µF to 47 µF, as confirmed in Typical Characteristics Figure 16 (Inrush Current). Discharge time scales with COUT value but remains functional across the full recommended range-no minimum or maximum capacitor limit is imposed for this feature.
Can RP118N201D-TR-FE replace RP118N201B-TR-FE without hardware changes?
Yes-pinout, footprint, and electrical specifications (except CE behavior) are identical. The only difference is that the 'D' version actively discharges VOUT when CE is low, while the 'B' version floats it. No PCB change is needed, but firmware must account for faster VOUT decay if downstream logic relies on hold-up time.
Is a separate input capacitor mandatory, and what value is recommended?
Yes-a minimum 1.0 µF ceramic capacitor (X5R/X7R) is required between VDD and GND, placed within 2 mm of the pins. This suppresses high-frequency noise from source impedance and prevents instability during CE toggling or load transients, as specified in Technical Notes section of the datasheet.
