Product details
Overview
TPS60301DGSR from Texas Instruments is a dual-output, regulated charge pump DC-DC converter designed for space-constrained, single-cell battery-powered systems. It generates a precise 3-V ±4% output (OUT2) and a 2×VIN unregulated output (OUT1), supports up to 20 mA on OUT2 and 40 mA on OUT1, operates from 0.9 V to 1.8 V input, and delivers up to 90% efficiency - enabling use in hearing instruments and portable smart card readers.
For engineers reviewing the TPS60301DGSR datasheet, TPS60301DGSR pinout, TPS60301DGSR application, or TPS60301DGSR equivalent, key selection criteria include its open-drain power-good output, ultra-low 35 µA quiescent current, LinSkip mode for light-load efficiency, 10-pin VSSOP package, and compatibility with 1-µF ceramic capacitors only - critical for low-noise, inductorless designs in medical and metering applications.
Technical Context
The TPS60301DGSR implements a two-stage switched-capacitor architecture: first stage doubles VIN to generate OUT1; second stage quadruples VIN (via 3×/4× auto-selection) to regulate OUT2 at 3 V. It operates in LinSkip mode - seamlessly transitioning between pulse-skipping (low IQ) and constant-frequency linear regulation based on load current threshold (~7.5 mA at VIN = 1.25 V).
Its integrated power-good comparator monitors OUT2 voltage, asserting PG low when <98% of nominal and high when ≥98%, with open-drain output requiring external pull-up. Shutdown via EN reduces supply current to 0.05 µA and isolates load from battery, extending shelf life - essential for intermittent-use portable devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 0.9 V to 1.8 V - supports single alkaline/NiMH/NiCd cell across full discharge curve. |
| OUT2 Output Voltage | 3.0 V ±4% - tightly regulated rail for MCU core or analog sensors requiring stable 3-V supply. |
| OUT2 Max Output Current | 20 mA - sufficient for MSP430-based metering or hearing aid DSP subsystems. |
| Quiescent Current | <35 µA - enables multi-year battery life in always-on low-duty-cycle applications. |
| Switching Frequency | 470–900 kHz - high frequency allows use of tiny 1-µF ceramic flying/output capacitors; no inductors needed. |
| Power-Good Output | Open-drain - requires external pull-up (100 kΩ–1 MΩ) to OUT1 or OUT2 for sequencing or reset assertion. |
| Shutdown Current | 0.05 µA - ensures negligible battery drain during storage or deep sleep modes. |
Pinout & Package
TPS60301DGSR is housed in a micro-small 10-pin VSSOP (DGS) package measuring 3.05 mm × 4.98 mm, optimized for high-density PCB layouts in portable medical and instrumentation devices.

| VIN | Supply input | Accepts 0.9–1.8 V battery source; bypassed with ≥1-µF ceramic capacitor to GND. |
| C1+, C1− | Flying capacitor 1 terminals | Form first charge-pump stage; connect to 1-µF ceramic capacitor for 2×VIN generation at OUT1. |
| OUT1 | Unregulated 2×VIN output | Delivers up to 40 mA; used for biasing analog circuitry or powering non-critical peripherals. |
| OUT2 | Regulated 3-V output | Main system rail; supplies microcontrollers, ADCs, or RF front-ends requiring tight voltage tolerance. |
| C2+, C2− | Flying capacitor 2 terminals | Form second charge-pump stage; connect to 1-µF ceramic capacitor for regulated 3-V generation. |
| GND | Ground reference | Common return for all internal circuits and external capacitors; must be low-impedance plane. |
| PG | Power-good output | Open-drain signal indicating OUT2 is within 98% of 3-V regulation; used for system reset or enable sequencing. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output charge pump applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60300DGSR | Identical pinout and electrical specs, but outputs 3.3 V ±4% on OUT2 instead of 3 V. | Suitable where system requires 3.3-V logic compatibility (e.g., interfacing with 3.3-V UART or SPI peripherals). | Select TPS60300DGSR if main rail must be 3.3 V; otherwise TPS60301DGSR is optimal for 3-V MCU cores. |
| TPS60303DGSR | Same 3-V OUT2, but features push-pull (not open-drain) PG output - eliminates need for external pull-up resistor. | Better suited for systems requiring active-high reset signaling without additional passives or where PG drives logic inputs directly. | Choose TPS60303DGSR when simplifying BOM and reducing layout complexity is prioritized over PG flexibility. |
Compared with TPS60300DGSR and TPS60303DGSR, the TPS60301DGSR uniquely balances 3-V regulation accuracy, open-drain PG configurability, and lowest quiescent current - making it the preferred choice for battery-critical 3-V embedded systems where design flexibility and long shelf life are mandatory.

FAQ
What is the regulated output voltage of the TPS60301DGSR?
The TPS60301DGSR provides a regulated 3.0-V ±4% output on pin OUT2, maintained across input voltages from 0.9 V to 1.8 V and output loads up to 20 mA. This specification is verified per TI's SLVS302B datasheet, with typical performance showing 2.88 V to 3.12 V under full operating conditions - ensuring compatibility with 3-V microcontrollers and analog sensors.
Does the TPS60301DGSR require inductors?
No, the TPS60301DGSR is an inductorless charge pump converter. It uses only five external 1-µF ceramic capacitors - two flying capacitors (C1F, C2F), one input capacitor (CIN), and two output capacitors (COUT1, COUT2). This eliminates magnetic components, reduces EMI, and enables ultra-compact PCB layouts ideal for hearing aids and smart card readers.
How does the power-good (PG) output function on the TPS60301DGSR?
The TPS60301DGSR features an open-drain PG output that goes high when OUT2 reaches ≥98% of its nominal 3-V value, and low when below regulation or during shutdown. An external pull-up resistor (100 kΩ–1 MΩ to OUT1 or OUT2) is required. This signal enables reliable power-up sequencing and system reset in MSP430-based metering and portable instrumentation designs.
What is the quiescent current of the TPS60301DGSR under no-load conditions?
The TPS60301DGSR draws less than 35 µA of quiescent current with no load and VIN = 1.8 V, as specified in the SLVS302B datasheet. In shutdown mode (EN = low), supply current drops further to just 0.05 µA - a critical feature for extending battery life in always-on, intermittently active devices like home-automation sensors and hearing instruments.
Can the TPS60301DGSR operate from a single alkaline battery?
Yes, the TPS60301DGSR is explicitly designed for single-cell alkaline, NiMH, or NiCd batteries, supporting input voltages from 0.9 V to 1.8 V. Its ability to regulate 3 V down to 0.9 V input enables full utilization of the battery's discharge curve - delivering >100 hours of continuous operation at 20 mA load with a 2000-mAh alkaline cell, as documented in TI's application data.
