Product details
Overview
TPS7A0510PYKAR from Texas Instruments is a 1-µA ultralow IQ, 200-mA low-dropout regulator in a 0.65-mm × 0.65-mm 4-pin DSBGA (YKA) package, delivering fixed 1.0-V output with ±1% typical accuracy and 235 mV max dropout at 200 mA - optimized for battery-powered wearable electronics and always-on power rails.
For engineers reviewing the TPS7A0510PYKAR datasheet, TPS7A0510PYKAR pinout, TPS7A0510PYKAR application, or TPS7A0510PYKAR equivalent, key selection criteria include quiescent current (1 µA typ), shutdown current (100–300 nA), active output discharge, stability with ≥0.47-µF ceramic output capacitor, and operation across –40°C to +125°C junction temperature.
Technical Context
The TPS7A0510PYKAR employs a PMOS pass transistor architecture enabling ultralow quiescent current independent of load, with integrated foldback current limiting and thermal shutdown (160°C trip). Its enable pin (VEN) accepts logic-level control (0.9 V high, 0.4 V low) and supports direct tie-to-IN when unused.
It features active pulldown circuitry for rapid output discharge during disable, and achieves excellent transient response due to internal compensation stable with 0.47–22 µF output capacitance - no external compensation required. Input voltage range spans 1.4 V to 5.5 V, supporting single-cell Li-ion, Li-primary, and 2–3-cell alkaline sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0 V ±1% typical accuracy ensures precise biasing for ultra-low-power MCUs and sensors. |
| Max Output Current | 200 mA continuous delivery supports moderate-power peripherals without thermal derating in YKA package. |
| Quiescent Current | 1 µA typical (3 µA max) extends battery life in multi-year IoT endpoint applications. |
| Dropout Voltage | 235 mV max at 200 mA (1.0 VOUT) enables regulation from 1.235 V input - critical for aging battery operation. |
| Ground Current | 6 µA typical at 200 mA load confirms minimal overhead current, preserving system efficiency. |
| Input Voltage Range | 1.4 V to 5.5 V accommodates wide chemistries: Li-SOCl₂ (3.6 V), Li-MnO₂ (3.0 V), and dual-alkaline (3.0 V). |
| Operating Temp | –40°C to +125°C junction rating qualifies for industrial and automotive cabin ambient environments. |
Pinout & Package
TPS7A0510PYKAR uses the YKA package: 0.65-mm × 0.65-mm, 4-pin DSBGA with 0.35-mm pitch and bottom-side ball layout (A1, A2, B1, B2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (A1) | Input supply connection | Accepts 1.4–5.5 V; requires ≥1 µF ceramic capacitor to GND placed adjacent to pin for EMI suppression and transient response. |
| OUT (A2) | Regulated output | Delivers stable 1.0 V; requires ≥0.47 µF ceramic capacitor to GND - smaller than typical LDOs, reducing board area. |
| EN (B1) | Enable control input | Logic-high (>0.9 V) enables regulator; logic-low (<0.4 V) disables with 100–300 nA shutdown current and active pulldown. |
| GND (B2) | Power ground reference | Must connect directly to low-impedance PCB ground plane; thermal pad (exposed underside) is electrically isolated but requires grounding for thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow IQ | 1 µA typical quiescent current enables >10-year battery life in coin-cell–powered devices (e.g., BLE sensors). |
| Active Output Discharge | Integrated pulldown resistor (120 Ω typ) discharges OUT to GND within microseconds upon disable - prevents floating rail issues. |
| Small-footprint DSBGA | 0.65 mm × 0.65 mm footprint saves >75% board area vs. SOT-23, critical for wearables and hearing aids. |
| Stable with Low-COUT | Guaranteed stability with 0.47 µF ceramic output capacitor eliminates need for larger, costly tantalum or polymer caps. |
| Foldback Current Limit | Reduces short-circuit power dissipation by lowering current under overload - enhances reliability during fault conditions. |
Applications
| Wearable Health Sensors | Always-On MCU Power Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A0512PYKAR | Fixed 1.2-V output; identical IQ, package, and specs otherwise. | Used where downstream logic requires 1.2 V (e.g., certain LP DDR I/O), not 1.0 V. | Select only if target voltage matches - not a drop-in replacement for 1.0-V systems. |
| MCP1700T-1002E/TT | 1.0-V fixed output, 1.6-µA IQ (typ), SOT-23-3 package, 250-mA rating, no EN pin or active discharge. | Suitable for cost-sensitive, non-EN-requiring designs where board space is less constrained. | Choose when enable control and ultra-small size are unnecessary; verify 250-mA capability meets peak load. |
Compared with TPS7A0510PYKAR, the TPS7A0512PYKAR offers identical performance at 1.2 V for voltage-flexible designs, while the MCP1700T-1002E/TT trades EN functionality and 0.65-mm footprint for lower unit cost and simpler 3-pin integration - requiring layout and feature reassessment.

FAQ
What is the minimum input voltage required for TPS7A0510PYKAR to regulate 1.0 V output?
The TPS7A0510PYKAR requires a minimum input voltage of 1.235 V to maintain regulation at full 200 mA load, based on its 235 mV maximum dropout voltage at that condition. At lighter loads, it can operate down to 1.4 V input per recommended operating conditions - sufficient for single Li-SOCl₂ or two-alkaline cells even at end-of-life.
Does TPS7A0510PYKAR require an external pull-up resistor on the EN pin?
No, the TPS7A0510PYKAR does not require an external pull-up on EN. When enable functionality is unused, the EN pin must be connected directly to IN to ensure permanent operation. The device draws only 10 nA at EN when VIN = 5.5 V, so no additional biasing is needed.
Can TPS7A0510PYKAR be used with a 0.22-µF output capacitor?
No - the TPS7A0510PYKAR is specified and guaranteed stable only with output capacitors of 0.47 µF or larger. Using 0.22 µF violates the minimum COUT requirement and may cause oscillation or poor transient response, especially under load steps. Always use ≥0.47 µF X7R/X5R ceramic capacitor.
What is the thermal performance of TPS7A0510PYKAR in the YKA package?
In the YKA (DSBGA) package, the TPS7A0510PYKAR has a junction-to-board thermal resistance (RθJB) of 66.9°C/W. With proper PCB copper pour under the thermal pad, it sustains 200 mA continuous output at +85°C ambient without exceeding 125°C junction temperature - verified per TI's thermal characterization data.
Is TPS7A0510PYKAR compatible with lead-free reflow profiles?
Yes, the TPS7A0510PYKAR in YKA package is rated for standard lead-free reflow (JEDEC J-STD-020, peak 260°C). Its 0.35-mm pitch and solder-ball construction are qualified for Type II (SnAgCu) paste and standard reflow oven profiles - no special process adjustments required.
