Product details
Overview
TCR5RG09A,LF from Toshiba Electronic Devices & Storage Corporation is a CMOS low-dropout linear regulator delivering fixed 0.9 V output at up to 500 mA, featuring ultra-high ripple rejection (100 dB @1 kHz), 150 mV typical dropout at 500 mA, and operation from 1.8–5.5 V input. It integrates overcurrent protection, thermal shutdown, auto-discharge, and supports ceramic capacitors (1.0 μF input/output), targeting power-sensitive portable electronics.
For engineers reviewing the TCR5RG09A,LF datasheet, TCR5RG09A,LF pinout, TCR5RG09A,LF application, or TCR5RG09A,LF equivalent, this page provides verified electrical specifications, WCSP4F package layout, real-world load transient behavior, noise performance (5 μVrms), and selection guidance against comparable LDOs for space-constrained battery-powered designs.
Technical Context
The TCR5RG09A,LF implements a bandgap-referenced CMOS pass transistor with integrated low-pass filtering for high-frequency ripple suppression. Its control logic enables ON/OFF functionality via a dedicated CONTROL pin with internal pull-down, and its bias current dynamically scales with output load to balance quiescent consumption and regulation performance.
Thermal shutdown activates at 160°C junction temperature with hysteresis (140°C recovery), while overcurrent protection limits output to 700 mA typical. The device operates across –40°C to +85°C ambient and maintains ±36 mV output accuracy for 0.9 V output under full 1–500 mA load range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 0.9 V ±36 mV - stable reference for low-voltage logic rails and RF biasing. |
| Max Output Current | 500 mA - sufficient for powering microcontrollers, sensors, and wireless transceivers in compact devices. |
| Ripple Rejection | 100 dB @1 kHz - suppresses switching noise from DC-DC converters feeding the LDO input. |
| Dropout Voltage | 150 mV typ. @500 mA - enables operation with minimal VIN–VOUT margin, extending battery life. |
| Quiescent Current | 7 μA typ. @0 mA - preserves battery capacity during system sleep modes. |
| Output Noise | 5 μVrms (10 Hz–100 kHz) - critical for noise-sensitive analog circuits like ADCs and RF front-ends. |
| Package | WCSP4F (0.645 mm × 0.645 mm, 0.33 mm max height) - ultra-miniature footprint for HDI PCBs. |
Pinout & Package
TCR5RG09A,LF uses the WCSP4F wafer-level chip-scale package: 0.645 mm × 0.645 mm body, 4 solder bumps, 0.33 mm max thickness, 0.26 mg typical weight. Mounting requires standard reflow profile for Pb-free WCSP components.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input voltage supply | Accepts 1.8–5.5 V; must be decoupled with ≥1.0 μF ceramic capacitor near pin. |
| VOUT | Regulated output | Delivers stable 0.9 V; requires ≥1.0 μF ceramic capacitor directly at pin for stability. |
| CONTROL | Enable/disable control | Logic-high (>0.9×VIN) enables regulator; logic-low (≤0.5 V) disables output and activates auto-discharge. |
| GND | Ground reference | Common return path for input, output, and control; must connect to low-impedance ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small WCSP4F package | 0.645 mm × 0.645 mm footprint enables placement in <1 mm² board area-ideal for wearables and hearing aids. |
| 100 dB ripple rejection @1 kHz | Rejects >99.999% of 1 kHz ripple amplitude-critical when LDO follows noisy buck converter stages. |
| Auto-discharge function | Internal 30 Ω discharge path rapidly drains VOUT capacitor when disabled-prevents residual voltage hold-up in power sequencing. |
| Low-noise 5 μVrms output | Enables clean power for precision analog blocks without external filtering-reduces BOM count and layout complexity. |
| Pull-down on CONTROL pin | Ensures default OFF state at power-up-eliminates need for external pull-down resistor in most applications. |
Applications
| Wireless Earbuds Power Rail | Wearable Sensor Node Core Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R1190H091B-TR-FE | 0.9 V fixed output, 500 mA, SOT-23-5 package (2.9 mm × 2.8 mm), 70 dB PSRR @1 kHz, 12 μA IQ | Larger footprint; lower PSRR reduces noise filtering capability in multi-stage power systems | Select when board space permits larger package and cost sensitivity outweighs PSRR/noise requirements |
| MCP1703T-0902E/MB | 0.9 V fixed output, 250 mA, SOT-23-3 package, 65 dB PSRR @1 kHz, 4 μA IQ, no enable pin | Half the current rating; lacks CONTROL pin and auto-discharge-unsuitable for sequenced power-down | Choose only for ultra-low-IQ, low-current applications without active enable control or fast discharge needs |
Compared with R1190H091B-TR-FE and MCP1703T-0902E/MB, the TCR5RG09A,LF delivers superior noise immunity (100 dB vs ≤70 dB), smaller size (WCSP4F vs SOT-23), and integrated enable/discharge-making it optimal for next-gen portable devices demanding miniaturization and clean power.

FAQ
What is the maximum input voltage rating for the TCR5RG09A,LF?
The TCR5RG09A,LF has an absolute maximum input voltage of 6.0 V, but its recommended operating input voltage range is 1.8 V to 5.5 V. Exceeding 5.5 V may compromise reliability or trigger overvoltage stress even if within absolute ratings. For stable 0.9 V output, VIN must be ≥1.8 V per datasheet Note 9, and the dropout headroom must accommodate the 150 mV typical VDO at full load.
Does the TCR5RG09A,LF require external capacitors, and what values are recommended?
Yes, the TCR5RG09A,LF requires ≥1.0 μF ceramic capacitors on both VIN and VOUT pins for stability and optimal transient response. Toshiba explicitly validates performance with 1.0 μF X5R/X7R ceramics, and recommends placing them as close as possible to the device terminals. Larger values (e.g., 4.7 μF) improve load transient behavior but are not required for basic operation.
How does the CONTROL pin function on the TCR5RG09A,LF?
The CONTROL pin enables or disables the TCR5RG09A,LF regulator: applying ≥0.9×VIN turns it ON, while ≤0.5 V turns it OFF and activates internal auto-discharge (30 Ω path to GND). An internal pull-down ensures default OFF at power-up, eliminating need for external resistors. This supports precise power sequencing in multi-rail systems.
What is the output voltage accuracy specification for the TCR5RG09A,LF?
The TCR5RG09A,LF guarantees output voltage accuracy of ±36 mV over the full operating temperature range (–40°C to +85°C) and 1–500 mA load current. This corresponds to ±4.0% tolerance on the 0.9 V nominal output, verified per Electrical Characteristics Table (Note 3) and confirmed in the Dropout Voltage table footnote.
Can the TCR5RG09A,LF be used in automotive applications?
No, the TCR5RG09A,LF is not qualified for automotive use. Its operating temperature range is –40°C to +85°C (ambient), and it lacks AEC-Q200 qualification, extended temperature testing, or automotive-specific reliability data. Toshiba explicitly restricts use in safety-critical systems including automotive ECUs, ADAS, and infotainment-see "Restrictions on Product Use" section of the datasheet.
