Product details
Overview
RP512Z201C-TR-F from Ricoh Electronics is a 2.0 V to 5.5 V input, 2.0 V fixed-output buck DC/DC converter with 0.3 µA ultra-low quiescent current, 300 mA output capability, and VFM control mode. It uses WLCSP-8-P1 packaging (1.45 mm × 1.48 mm, 0.4 mm max thickness) and targets battery-powered wearable and IoT devices requiring minimal standby power and ultra-compact footprint.
For engineers reviewing the RP512Z201C-TR-F datasheet, RP512Z201C-TR-F pinout, RP512Z201C-TR-F application, or RP512Z201C-TR-F equivalent, this page delivers verified technical context, package-specific pin functions, real-world efficiency vs. load curves, confirmed auto-discharge behavior (C-version), and validated alternatives for low-power DC/DC replacement in coin-cell and Li-ion systems.
Technical Context
The RP512Z201C-TR-F implements variable-frequency modulation (VFM) control to sustain 0.3 µA IQ across light-load conditions while maintaining ±1.5% output voltage accuracy at VSET ≥ 1.2 V. Its integrated PMOS/NMOS power switches exhibit 0.15 Ω on-resistance at VIN = 3.6 V, enabling high-efficiency operation down to 1 mA load.
It features undervoltage lockout (UVLO) with 1.55 V rising threshold and 1.40 V falling threshold, 10 ms soft-start time, and active-high CE pin with 1.0 V logic-high threshold. The C-version lacks auto-discharge functionality, distinguishing it from D-version variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.0 V to 5.5 V - supports direct operation from coin cells (e.g., CR2032) and USB ports without pre-regulation. |
| Output Voltage | Fixed 2.0 V (±1.5% accuracy) - tightly regulated for powering low-voltage MCUs, BLE radios, and sensors. |
| Quiescent Current | 0.3 µA - enables multi-year battery life in always-on wearable applications (e.g., health monitors). |
| Output Current | 300 mA continuous - sufficient for mixed-signal SoCs and RF transceivers during burst transmission. |
| Switching Control | VFM (Variable Frequency Modulation) - dynamically adjusts frequency to maintain >85% efficiency at 100 µA load (VIN = 3.6 V). |
| Package | WLCSP-8-P1 (1.45 mm × 1.48 mm, 0.4 mm max height) - enables integration into space-constrained IC cards and thin wearables. |
| Standby Current | 0.01 µA - near-zero leakage when CE = low, critical for long-term storage and wake-on-event designs. |
Pinout & Package
RP512Z201C-TR-F is housed in a WLCSP-8-P1 package (1.45 mm × 1.48 mm, 0.4 mm max thickness) with bottom-side GND tab electrically connected to substrate. Thermal performance is enhanced when the tab is soldered to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, B1 | VIN | Dual-input power pins reduce trace inductance and improve high-frequency decoupling stability. |
| C1 | LX | Switch node connecting internal PMOS/NMOS to external inductor; requires short, low-inductance routing. |
| A2 | VOUT | Regulated 2.0 V output; connects directly to load and bulk capacitor (22 µF recommended). |
| C2, B3, C3 | GND | Three ground terminals minimize ground bounce and support low-noise feedback loop stability. |
| A3 | CE | Active-high enable pin (1.0 V logic-high threshold); open-circuit state is undefined - must be pulled high or low. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ operation | 0.3 µA operating current enables >10-year battery life in 20 µA average-load wearable devices. |
| Miniaturized total solution size | 10.6 mm² board area including CIN (10 µF), COUT (22 µF), and L (2.2 µH) - fits sub-12 mm² wearable PCBs. |
| Wide input compatibility | 2.0–5.5 V range supports single-cell Li-ion (2.7–4.2 V), alkaline (up to 3.2 V), and USB 5 V sources. |
| Integrated power switches | 0.15 Ω PMOS/NMOS on-resistance reduces conduction loss and eliminates need for external MOSFET drivers. |
| Robust start-up behavior | 10 ms soft-start prevents inrush current spikes; UVLO ensures clean power sequencing below 1.55 V VIN. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62740DRYR | 0.36 µA IQ, 300 mA, 1.8–5.5 V IN, fixed 2.0 V out; DSBGA-6 package (1.0 mm × 1.0 mm) | Smaller footprint but no LX pin access; lacks UVLO hysteresis and soft-start programmability. | Prefer for space-constrained designs where full switch-node control is unnecessary. |
| MAX17222ELT+T | 0.6 µA IQ, 400 mA, 0.7–5.5 V IN, adjustable/fixed outputs; 6-bump WLP (1.22 mm × 0.83 mm) | Lower minimum input (0.7 V) enables single NiMH cell use; higher IQ reduces battery lifetime by ~2× vs. RP512Z. | Choose when input may dip below 2.0 V or when higher output current headroom is required. |

Manufacturer
Ricoh Electronics is a Japanese semiconductor manufacturer specializing in high-efficiency power management ICs for portable and ultra-low-power applications.

FAQ
Is RP512Z201C-TR-F still in active production?
No - RP512Z201C-TR-F is officially discontinued per Ricoh document EA-400-251006. However, Aetrix Electronics maintains legacy inventory and offers lifecycle management support, including cross-reference guidance and last-time-buy coordination for ongoing production programs.
What distinguishes the 'C' version from the 'D' version in RP512Zxx1x naming?
The 'C' suffix indicates absence of auto-discharge functionality: when CE is pulled low, the output discharges only through external load/COUT leakage. The 'D' version integrates an NMOS discharge switch (RON ≈ 60 Ω) to actively pull VOUT to 0 V within milliseconds, critical for safety-critical shutdown sequences.
Can RP512Z201C-TR-F operate from a 1.8 V input source?
No - the absolute minimum input voltage is 2.0 V per Recommended Operating Conditions. Below 2.0 V, UVLO engages (VUVLOF = 1.40–1.65 V), halting switching. Attempting operation at 1.8 V results in unregulated dropout and potential instability due to insufficient gate drive margin for internal MOSFETs.
Which external components are mandatory for stable operation?
Mandatory components are: 10 µF ceramic CIN (placed within 1 mm of VIN/GND pins), 22 µF ceramic COUT (rated ≥3× VOUT), and 2.2 µH shielded inductor with ≥300 mA saturation current. Layout requires shortest possible LX and GND traces, and thermal pad connection to PCB ground plane for WLCSP-8-P1.
