Product details
Overview
TPS7A0515PDBVR from Texas Instruments is an ultralow-quiescent-current (1 µA typ) 200-mA low-dropout regulator in a 1.0-mm × 1.0-mm X2SON-4 package, delivering fixed 1.5-V output with ±1% typical accuracy and 235 mV max dropout at 200 mA. It supports battery-powered wearable electronics and always-on subsystems powered by Li-ion or alkaline cells.
For engineers reviewing the TPS7A0515PDBVR datasheet, TPS7A0515PDBVR pinout, TPS7A0515PDBVR application, or TPS7A0515PDBVR equivalent, key selection criteria include ultralow IQ for multi-year battery life, active output discharge for clean power sequencing, stability with ≥0.47-µF ceramic output capacitors, and operation across –40°C to +125°C junction temperature.
Technical Context
The TPS7A0515PDBVR employs a PMOS pass transistor architecture enabling ultra-low dropout and near-zero reverse current during shutdown. Its internal reference and error amplifier maintain tight output regulation under load transients up to 200 mA with minimal output voltage deviation.
It integrates an enable input with logic-level thresholds (VEN(HI) = 0.9 V, VEN(LO) = 0.4 V), thermal shutdown (160°C trip), foldback current limiting, and an active pulldown circuit that discharges the output via a 120-Ω internal resistor when disabled - critical for systems requiring rapid rail collapse.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±1% (typ), ±3% (max) - ensures stable core/logic supply without external feedback components. |
| Quiescent Current | 1 µA (typ), 3 µA (max) - extends shelf life and runtime in battery-backed or energy-harvested systems. |
| Max Output Current | 200 mA - sufficient for microcontrollers, sensors, and RF modules in compact portable devices. |
| Dropout Voltage | 235 mV (max) at 200 mA - enables regulation from 1.735 V input, compatible with single-cell Li-ion (2.7–4.2 V) and two-cell alkaline (2.0–3.2 V). |
| Input Voltage Range | 1.4 V to 5.5 V - supports wide battery chemistries including Li-SOCl₂, Li-MnO₂, and 2–3-cell alkaline. |
| Output Capacitor | Stable with ≥0.47 µF ceramic - reduces BOM count and PCB area vs. larger electrolytic solutions. |
| Operating Temperature | –40°C to +125°C (TJ) - qualified for automotive cabin, industrial control, and outdoor IoT deployments. |
Pinout & Package
TPS7A0515PDBVR uses the 1.0-mm × 1.0-mm, 4-pin X2SON (DQN) package with wettable flank leads for automated optical inspection. The package has no exposed thermal pad; the die attach paddle is electrically isolated and must not be connected.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output | Delivers 1.5 V; requires ≥0.47-µF ceramic capacitor to GND placed adjacent to pin for stability and transient response. |
| 2 (GND) | Ground reference | Primary return path for load current and internal bias; must connect directly to low-impedance system ground plane. |
| 3 (EN) | Enable control input | Active-high logic input; tie to IN if always-on operation required; drives output to high-Z and activates pulldown when <0.4 V. |
| 4 (IN) | Input supply | Accepts 1.4–5.5 V; requires ≥1-µF ceramic capacitor to GND placed as close as possible to minimize input impedance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow IQ (1 µA typ) | Reduces standby power loss to <1.5 nW per µA of supply voltage - critical for >10-year battery life in coin-cell applications. |
| Active output discharge | 120-Ω internal pulldown resistor collapses VOUT within microseconds after EN deassertion - prevents floating rails and unintended wake-up. |
| Ultra-small X2SON-4 package | 1.0 mm × 1.0 mm footprint with 0.4-mm pitch - saves >60% board area vs. SOT-23 while maintaining thermal performance (RθJA = 144.1°C/W). |
| Foldback current limit | Reduces short-circuit current to ~65 mA at VOUT = 0 V - protects IC and source during fault conditions without external current-sense circuitry. |
| Wide input range (1.4–5.5 V) | Eliminates need for pre-regulation stages when interfacing with diverse battery types - simplifies power tree design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-quiescent-current LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A0515PDQNR | Same electrical specs and X2SON-4 package, but tape-and-reel packaging (3,000 pcs/reel vs. 3,000 pcs/reel for PDBVR); identical thermal and electrical behavior. | No functional difference - used interchangeably in production; PDQNR preferred for high-volume SMT lines. | Select PDQNR for automated assembly; PDBVR for prototyping or low-volume hand-soldering due to smaller reel size. |
| MCP1700T-1502E/TT | 1.5-V fixed LDO with 1.6-µA IQ (typ), 250-mA rating, SOT-23-3 package; lacks EN pin and active discharge; dropout 375 mV @ 250 mA. | Suitable for always-on, non-sequenced rails where enable control and fast discharge are unnecessary. | Choose MCP1700T-1502E/TT only when board space allows SOT-23-3 and EN/discharge features are omitted from system requirements. |
Compared with TPS7A0515PDQNR, the TPS7A0515PDBVR offers identical performance in a functionally equivalent package but differs only in reel packaging format; versus MCP1700T-1502E/TT, it delivers lower dropout, integrated enable, and active discharge - essential for modern low-power architectures.

FAQ
What is the maximum input voltage rating for the TPS7A0515PDBVR?
The TPS7A0515PDBVR has an absolute maximum input voltage of 6.0 V. However, its recommended operating input range is 1.4 V to 5.5 V. Exceeding 5.5 V may cause permanent damage or violate safe operating area limits, especially at elevated temperatures. Always ensure VIN remains within this range during normal operation and transient events.
Does the TPS7A0515PDBVR require an external pull-up resistor on the EN pin?
No, the TPS7A0515PDBVR does not require an external pull-up on EN. When enable functionality is not needed, the EN pin must be directly connected to IN to guarantee proper operation. The device draws only 10 nA from EN at 5.5 V, so no external biasing is necessary - simplifying schematic design and reducing component count.
Can the TPS7A0515PDBVR operate with a 0.22-µF output capacitor?
No - the TPS7A0515PDBVR is specified and tested for stability with ≥0.47-µF ceramic output capacitance. Using 0.22 µF violates the minimum requirement and risks oscillation, poor transient response, or startup failure. TI recommends 1-µF X7R/X5R ceramics for optimal performance across temperature and voltage.
What is the purpose of the active pulldown resistor in the TPS7A0515PDBVR?
When the EN pin is driven low (<0.4 V), the TPS7A0515PDBVR activates an internal 120-Ω pulldown resistor between OUT and GND. This rapidly discharges the output capacitor, preventing residual voltage from holding downstream circuitry in undefined states - essential for reliable power sequencing and low-power wake-up integrity in the TPS7A0515PDBVR.
Is the TPS7A0515PDBVR RoHS-compliant and lead-free?
Yes, the TPS7A0515PDBVR is RoHS-compliant and lead-free per TI's official product documentation. It meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and is compatible with standard Pb-free reflow profiles. Full compliance data, including REACH and conflict minerals statements, is available in TI's official product folder for the TPS7A0515PDBVR.
