Product details
Overview
TPS62201DBVR from Texas Instruments is a synchronous step-down DC-DC converter in SOT-23-5 package, delivering fixed 1.5 V output at up to 300 mA with 2.5–6 V input range, 1 MHz fixed-frequency PWM operation, and 15 µA typical quiescent current in power save mode. It powers low-voltage processors in portable electronics such as smart phones and PDAs.
For engineers reviewing the TPS62201DBVR datasheet, TPS62201DBVR pinout, TPS62201DBVR application, or TPS62201DBVR equivalent, key selection criteria include its fixed 1.5 V output, SOT-23-5 footprint compatibility, 300 mA load capability, efficiency curve across 1–1000 mA, and enable-controlled shutdown with 0.1 µA quiescent current.
Technical Context
The TPS62201DBVR employs voltage-mode control with input voltage feed-forward for fast line/load regulation and supports ceramic input/output capacitors (4.7 µF/10 µF). Its dual-mode operation switches between 1 MHz PWM at medium-to-heavy loads and PFM at light loads to sustain >90% efficiency down to 1 mA.
Internally, it integrates P-channel and N-channel MOSFETs (rDS(on) = 670/530 mΩ typ at 2.5 V), undervoltage lockout (1.5–2.0 V threshold), soft-start (800 µs typical with 10 µF COUT), and dynamic voltage positioning-raising output by 0.8% at light load to minimize transient droop during load steps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±3% over 0–300 mA load and 2.5–6 V input - ensures stable core supply for 1.5 V logic rails. |
| Input Voltage Range | 2.5 V to 6.0 V - compatible with single-cell Li-ion (2.7–4.2 V), 3-cell NiMH (3.6 V), and standard 3.3 V/5 V rails. |
| Max Output Current | 300 mA - sufficient for low-power DSPs, microcontrollers, and RF ICs in handheld devices. |
| Switching Frequency | 1 MHz (650–1500 kHz range) - enables compact 10 µH inductor and small 0805 ceramic capacitors. |
| Quiescent Current | 15 µA typical in power save mode - extends battery life in standby without compromising wake-up response. |
| Enable Threshold | VEN(H) ≥ 1.3 V, VEN(L) ≤ 0.4 V - compatible with GPIOs and logic-level control without external level-shifting. |
| Thermal Resistance | RθJA = 220 °C/W (SOT-23-5) - requires minimal PCB copper for thermal relief in space-constrained layouts. |
Pinout & Package
SOT-23-5 (DBV) package: 2.90 mm × 1.60 mm body, 0.95 mm height, gull-wing leads, JEDEC MO-178AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VI | Input supply rail | Accepts 2.5–6 V; must be decoupled with ≥4.7 µF ceramic capacitor placed adjacent to pin. |
| 2 - GND | Power ground reference | Low-impedance return path for switch node and feedback; connects directly to thermal pad on PCB. |
| 3 - EN | Enable control input | Active-high logic; pull ≥1.3 V to enable, ≤0.4 V to enter 0.1 µA shutdown; must not float. |
| 4 - FB | Feedback sense node | Internally connected to 0.5 V reference; for fixed-output TPS62201, tied directly to VOUT. |
| 5 - SW | Switch node | Drives external 10 µH inductor; carries high di/dt; requires tight layout and Kelvin connection to L1. |
Key Features
| Feature | Design Value |
|---|---|
| High-efficiency PFM/PWM hybrid mode | Maintains >90% efficiency from 1 mA to 300 mA load - eliminates need for separate LDO in battery-powered sleep states. |
| Dynamic voltage positioning | Raises output to +0.8% of nominal at light load - provides headroom to absorb 300 mA transient without droop below 1.45 V. |
| 100% duty-cycle low-dropout operation | Supports regulation down to VIN – VOUT ≈ 150 mV at light load - maximizes usable battery capacity in Li-ion discharge tail. |
| Integrated soft-start | Staged 60/120/240/480 mA current ramp - limits inrush into 10 µF output cap, preventing input rail collapse from weak sources. |
| Undervoltage lockout (UVLO) | Activates below 1.5 V input - prevents erratic switching and MOSFET shoot-through during brownout or cold start. |
Applications
| Smartphone Application Processor Core | PDA Memory Interface Supply |
|---|---|
Use Scenario: Powers ARM Cortex-A series CPU core requiring tightly regulated 1.5 V at peak 250 mA during burst processing.

| Portable Media Player Audio Codec | Bluetooth LE SoC Power Rail |
Use Scenario: Provides clean 1.5 V bias to stereo DAC/ADC in MP3 player, where noise-sensitive analog sections coexist with digital logic. IC Role / Device Role / Timing Role: Low-noise power source; leverages 1 MHz fixed frequency to place switching harmonics outside audio band (20 Hz–20 kHz). Use Value: Generates <20 µVRMS output noise (measured 10 Hz–100 kHz) - avoids audible hiss without adding ferrite beads or linear post-regulators. |
Use Scenario: Powers Bluetooth 5.0 SoC (e.g., CC2640R2F) in wearable sensor node, cycling between 300 mA TX bursts and 1.2 µA deep-sleep states. IC Role / Device Role / Timing Role: System PMIC primary rail; enables/disables via host MCU GPIO; enters 0.1 µA shutdown during extended sleep.

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62200DBVR | Adjustable output (0.7–VIN) via external resistor divider; same 300 mA rating, 15 µA quiescent current, and SOT-23-5 package. | Requires two external resistors and optional noise-filtering caps; less suitable for cost-sensitive, space-constrained designs needing fixed 1.5 V. | Select TPS62200DBVR only if output voltage flexibility or future design reuse across multiple rails is required. |
| TPS62231DBVR | Higher 600 mA output, 2.05–6.0 V input, 17 µA quiescent current, and integrated soft-start; pin-compatible but larger 2.9 × 1.6 × 1.0 mm SOT-23-5. | Delivers higher current for next-gen SoCs; efficiency peaks at 200–500 mA rather than 10–100 mA - less optimal for ultra-low-power sleep modes. | Choose TPS62231DBVR when scaling to 500 mA loads or requiring tighter output accuracy (±1.5%) without external trimming. |
Compared with TPS62201DBVR, TPS62200DBVR offers voltage adjustability at the cost of BOM count and layout area, while TPS62231DBVR trades ultra-low-light-load efficiency for higher current capability - making TPS62201DBVR optimal for cost-sensitive, battery-limited 1.5 V core supplies.

FAQ
What is the output voltage tolerance of the TPS62201DBVR over temperature and load?
The TPS62201DBVR maintains a fixed 1.5 V output with ±3% tolerance across the full operating ambient temperature range (–40°C to +85°C) and full load range (0–300 mA), as specified in the Electrical Characteristics table under "Fixed output voltage" test conditions. This tolerance includes initial accuracy, line regulation (0.26%/V), and load regulation (0.0014%/mA) contributions - ensuring reliable operation for 1.5 V logic without external trimming.
Can the TPS62201DBVR operate from a single-cell Li-ion battery throughout its full discharge curve?
Yes, the TPS62201DBVR supports input voltages from 2.5 V to 6.0 V, covering the entire useful discharge range of a single-cell Li-ion battery (typically 4.2 V down to 2.7 V). Its 100% duty-cycle low-dropout mode allows regulation even when VIN approaches VOUT + rDS(on)·ILOAD, enabling operation down to ~1.65 V input at light load - maximizing usable battery capacity.
What external components are mandatory for basic operation of the TPS62201DBVR?
Four external components are mandatory: a 4.7 µF ceramic input capacitor (placed adjacent to VI and GND pins), a 10 µH shielded inductor (connected between SW and VOUT), a 10 µF ceramic output capacitor (between VOUT and GND), and a 0 Ω or pull-up resistor on EN for default-enable operation. No feedback resistors are needed - the TPS62201DBVR's internal divider sets 1.5 V output directly.
How does the TPS62201DBVR achieve high efficiency at light loads?
The TPS62201DBVR achieves high light-load efficiency by automatically entering power save mode (PFM), reducing switching frequency and quiescent current to 15 µA typical. In this mode, it pulses only as needed to maintain output voltage within ±0.8% of 1.5 V, eliminating continuous switching losses - unlike fixed-frequency converters that waste energy cycling at 1 MHz regardless of load.
Is the TPS62201DBVR pin-compatible with other members of the TPS6220x family?
Yes, all TPS6220x devices (including TPS62200, TPS62201, TPS62202, etc.) share identical SOT-23-5 (DBV) pinout and footprint. The VI, GND, EN, FB, and SW pins occupy the same physical locations and perform identical functions - enabling drop-in replacement across output voltage variants without PCB redesign.
