Product details
Overview
TPS7A0515PYKAR from Texas Instruments is a 1.5-V fixed-output, ultralow-quiescent-current (1 µA typ) low-dropout regulator in a 0.65-mm × 0.65-mm 4-pin DSBGA (YKA) package, delivering up to 200 mA with 235 mV max dropout at full load and ±3% output accuracy over –40°C to +125°C - designed for battery-powered wearables and always-on subsystems.
For engineers reviewing the TPS7A0515PYKAR datasheet, TPS7A0515PYKAR pinout, TPS7A0515PYKAR application, or TPS7A0515PYKAR equivalent, key selection criteria include its 1-µA IQ, active output discharge, 0.47-µF minimum stable output capacitance, and compatibility with Li-SOCl₂, Li-MnO₂, and multi-cell alkaline batteries.
Technical Context
The TPS7A0515PYKAR employs a PMOS pass transistor architecture enabling ultralow quiescent current and fast transient response without requiring external compensation. Its enable-controlled shutdown reduces leakage to 300 nA max while activating internal pulldown for rapid output discharge.
It operates across 1.4 V to 5.5 V input range and maintains regulation down to 1.4 V input for 1.5-V output, with foldback current limiting and thermal shutdown (160°C trip) ensuring robustness in compact, thermally constrained layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±3% over –40°C to +125°C - ensures stable core/bias rail for low-power MCUs and sensors. |
| Max Output Current | 200 mA - sufficient for BLE SoCs, display drivers, and sensor hubs in space-constrained designs. |
| Quiescent Current | 1 µA typical, 3 µA max - extends shelf life and runtime in coin-cell or energy-harvesting applications. |
| Dropout Voltage | 235 mV max at 200 mA (1.5 VOUT) - enables operation from single Li-MnO₂ (nominal 3.0 V) or two alkaline cells (3.2 V). |
| Ground Current | 6 µA typical at 200 mA - minimizes total system supply current during active operation. |
| Stability | Stable with ≥0.47 µF ceramic output capacitor - eliminates need for large, costly bulk capacitors. |
| Enable Threshold | VEN(HI) = 0.9 V, VEN(LO) = 0.4 V - compatible with 1.2-V or 1.8-V logic-level control signals. |
Pinout & Package
TPS7A0515PYKAR uses the YKA package: 0.65-mm × 0.65-mm, 4-pin DSBGA with 0.35-mm pitch and bottom-side ball layout. Thermal pad is not electrically connected but must be soldered to PCB ground plane for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (A1) | Input supply | Accepts 1.4–5.5 V; requires ≥1 µF ceramic capacitor to GND placed adjacent to pin for EMI suppression and transient immunity. |
| EN (B1) | Enable control | Active-high logic input; float or tie to IN if always-on; drives <10 nA leakage, enabling direct MCU GPIO control. |
| GND (B2) | Power ground | Primary return path for input/output currents; must connect to low-impedance PCB ground plane. |
| OUT (A2) | Regulated output | Delivers 1.5 V ±3%; requires ≥0.47 µF ceramic capacitor to GND near pin for stability and load-transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow IQ | 1 µA typical quiescent current - enables >10-year battery life in 10-µA average-load IoT endpoints. |
| Active Output Discharge | Internal pulldown resistor (~120 Ω) discharges OUT to GND within microseconds upon disable - prevents floating bias in downstream circuitry. |
| Wide Input Range | 1.4 V to 5.5 V operation - supports direct connection to primary lithium, Li-ion, and 2–3-cell alkaline sources without pre-regulation. |
| Small Footprint | 0.42 mm² DSBGA package - saves >70% board area vs. SOT-23, critical for hearing aids and smart patches. |
| Thermal Robustness | Rated for –40°C to +125°C junction temperature with thermal shutdown at 160°C - suitable for automotive cabin and industrial edge nodes. |

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 |
|---|---|---|---|
| TPS7A0515PDBVR | SOT-23-5 package (2.9 mm × 1.6 mm); higher RθJA (185.6°C/W); no integrated pulldown resistor. | Requires external discharge circuit for fast turn-off; better suited for prototyping or boards with existing SOT-23 footprints. | Select when manual layout control of discharge path is preferred or when thermal margin exceeds 40°C/W. |
| MCP1703T-1502E/MB | 1.8-µA IQ (typ), 6-V max input, SOT-23-3 package; no enable pin or active discharge; ±2% accuracy. | Lacks EN control and output discharge - unsuitable for systems requiring precise power sequencing or fast wake/sleep transitions. | Choose only for cost-sensitive, non-sequenced always-on rails where 1.8-µA IQ is acceptable and footprint matches. |
Compared with TPS7A0515PDBVR and MCP1703T-1502E/MB, the TPS7A0515PYKAR uniquely combines sub-1-µA IQ, integrated active discharge, and 0.42-mm² DSBGA packaging - making it the only option for miniaturized, sequenced, battery-critical applications demanding <1-µA standby current.

FAQ
What is the maximum input voltage rating for the TPS7A0515PYKAR?
The TPS7A0515PYKAR 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 trigger internal protection or degrade reliability; sustained operation above 6.0 V risks permanent damage per the Absolute Maximum Ratings table in the SBVS254D datasheet.
Does the TPS7A0515PYKAR require an external pull-up on the EN pin?
No - the TPS7A0515PYKAR does not require an external pull-up on the EN pin. When enable functionality is unused, the EN pin must be directly connected to IN. The device draws only 10 nA at EN when VIN = 5.5 V, so no external bias is needed for reliable high-state assertion.
Can the TPS7A0515PYKAR operate with a 0.22-µF output capacitor?
No - the TPS7A0515PYKAR requires a minimum 0.47-µF ceramic output capacitor for stability, as specified in Section 6.3 (Recommended Operating Conditions). Using 0.22 µF risks oscillation, poor transient response, and potential output overshoot during load steps, violating the design requirements validated in TI's characterization data.
What is the thermal resistance (RθJA) of the TPS7A0515PYKAR in its YKA package?
The TPS7A0515PYKAR in the YKA (DSBGA) package has a junction-to-ambient thermal resistance (RθJA) of 198.0°C/W under standard JEDEC JESD51-7 conditions. This value assumes a 2-layer PCB with 1-in² copper pour connected to the thermal pad; actual performance improves with larger ground planes or internal layers.
Is the TPS7A0515PYKAR pin-compatible with other TPS7A05 variants like TPS7A0518PYKAR?
Yes - all TPS7A05 YKA-package variants (including TPS7A0515PYKAR and TPS7A0518PYKAR) share identical 4-ball DSBGA pinout (IN/A1, EN/B1, GND/B2, OUT/A2), same footprint, and identical thermal pad layout. Only the fixed output voltage differs; no PCB redesign is required when swapping between 1.5 V, 1.8 V, or other YKA options.
