Product details
Overview
HPA01091DBVR from Texas Instruments is a 300-mA, low-quiescent-current, low-dropout linear regulator in SOT-23-5 package, delivering 2.8 V output with ±2% accuracy, 35 μA quiescent current, and 75 mV dropout at 100 mA load. It supports battery-powered wireless handsets and Bluetooth devices requiring stable, low-noise power under light-to-moderate load.
For engineers reviewing the HPA01091DBVR datasheet, HPA01091DBVR pinout, HPA01091DBVR application, or HPA01091DBVR equivalent, key selection criteria include dropout voltage at 300 mA, PSRR at 1 kHz, thermal shutdown threshold, enable pin logic levels, and minimum stable output capacitance.
Technical Context
The HPA01091DBVR uses a PMOS pass transistor architecture to achieve low dropout and high PSRR (68 dB at 1 kHz), with internal bandgap reference and error amplifier ensuring ±2% DC output accuracy across –40°C to +125°C. Its undervoltage lockout activates at 1.9 V input to prevent erratic startup.
It integrates thermal shutdown (trip at +165°C, reset at +145°C) and current limiting (~500 mA typical), and operates stably with ≥0.1 μF effective ceramic output capacitance-enabling compact, cost-effective designs without requiring high-ESR bulk capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.8 V fixed, ±2% accuracy over full temperature and load range-ensures reliable biasing for 2.8-V logic or RF circuitry without external feedback. |
| Max Output Current | 300 mA continuous-supports moderate-power microcontrollers, sensors, or transceivers without derating in standard PCB layouts. |
| Dropout Voltage | 75 mV at 100 mA and 2.8 V output-enables operation down to VIN = 2.875 V, extending battery runtime in single-cell Li-ion systems. |
| Quiescent Current | 35 μA typical at no load-minimizes standby power loss critical for always-on IoT endpoints and wearable devices. |
| PSRR | 68 dB at 1 kHz-effectively suppresses switching noise from upstream DC/DC converters feeding sensitive analog or RF stages. |
| Enable Threshold | EN high at ≥0.9 V, low at ≤0.4 V-compatible with 1.8-V GPIOs and allows direct control from low-voltage microcontrollers. |
| Stable Capacitance | 0.1 μF effective ceramic output capacitance-permits use of small, low-cost X5R/X7R 0402 or 0603 capacitors without stability risk. |
Pinout & Package
SOT-23-5 (DBV) package: 2.9 mm × 1.6 mm × 1.15 mm body, surface-mount, lead-free, RoHS-compliant, moisture sensitivity level (MSL) 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output | Delivers 2.8 V to load; requires ≥0.1 μF ceramic capacitor to GND for stability and transient response. |
| 2 (GND) | Ground reference | Common return path for IN, OUT, and EN; must connect directly to low-impedance ground plane to maintain PSRR and noise performance. |
| 3 (IN) | Input supply | Accepts 2.0–5.5 V input; benefits from 0.1–1.0 μF ceramic capacitor to GND near pin to suppress source impedance effects. |
| 4 (N/C) | No connection | Internally unconnected; may be tied to GND for improved thermal dissipation but has no electrical function. |
| 5 (EN) | Enable control | Active-high digital input; pulls device into <1 μA shutdown when held ≤0.4 V, enabling precise power sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout voltage | 75 mV @ 100 mA enables >97% efficiency at 2.8 V output with 3.0 V input-critical for energy-constrained portable systems. |
| High PSRR | 68 dB at 1 kHz reduces ripple from noisy switchers, preserving signal integrity in audio, sensor, and RF front-end supplies. |
| Ultra-low IQ | 35 μA quiescent current extends battery life in sleep modes-e.g., adds <1.5 mAh/year drain on a 10-μA system standby current. |
| Thermal & current protection | Integrated shutdown at +165°C and current limit ~500 mA prevent damage during overload or poor heatsinking-no external circuitry needed. |
| Small-footprint stability | Stable with 0.1 μF effective output capacitance-allows use of 0402-size ceramics, saving board area vs. legacy LDOs requiring ≥2.2 μF. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV70228DBVR | Same family, identical 2.8 V output, SOT-23-5 package, same 35 μA IQ and 68 dB PSRR-but marked as TLV70228 (HPA01091 is TI internal part number; both share SLVSAG6B datasheet). | No functional difference; used interchangeably in production-same pinout, specs, and qualification. | Select TLV70228DBVR for standard TI ordering channels; HPA01091DBVR is functionally identical and supported under same TI documentation. |
| TPS7A0528DBVR | Lower IQ (25 μA), higher PSRR (75 dB @ 1 kHz), but 200-mA max output and 125-mV dropout @ 100 mA-less headroom than HPA01091DBVR. | Better for ultra-low-power sub-200-mA loads; unsuitable where 300-mA peak current or <100-mV dropout is required. | Choose TPS7A0528DBVR only if system load stays ≤200 mA and deeper battery discharge (down to 2.92 V input) is acceptable. |
Compared with TLV70228DBVR, HPA01091DBVR offers identical performance and compatibility; versus TPS7A0528DBVR, it trades 10 μA higher IQ for 100 mA extra output capacity and 47 mV lower dropout-making it preferable for 300-mA burst-load applications like RF transmission.

FAQ
What is the output voltage tolerance of the HPA01091DBVR over temperature and load?
The HPA01091DBVR maintains ±2% DC output accuracy across –40°C to +125°C junction temperature and 0–300 mA load range, as specified in the SLVSAG6B datasheet. This tolerance includes initial calibration, line regulation (≤5 mV), and load regulation (≤15 mV), ensuring consistent 2.8 V delivery in demanding environments.
Does the HPA01091DBVR require an input capacitor for stability?
No, the HPA01091DBVR does not require an input capacitor for stability, but TI recommends a 0.1–1.0 μF low-ESR ceramic capacitor from IN to GND to improve transient response and suppress source impedance effects-especially when the device is remote from the main power source or driving fast-switching loads.
What is the minimum output capacitance required for stable operation of the HPA01091DBVR?
The HPA01091DBVR is stable with an effective output capacitance of ≥0.1 μF, provided it is a ceramic type (e.g., X5R or X7R) with ESR <200 mΩ. This specification refers to capacitance under actual operating bias and temperature-not the rated value-so a 0.1-μF rated capacitor may not suffice if derated below 0.1 μF in-circuit.
How does the enable pin (EN) of the HPA01091DBVR behave during power-up and shutdown?
The HPA01091DBVR EN pin is active-high: the regulator enables when EN ≥0.9 V and shuts down when EN ≤0.4 V. During shutdown, ground current drops to ~1 μA, and the output is left floating (no active discharge). Startup time to 98% of 2.8 V is ≤100 μs with 1-μF COUT and 300-mA load.
Is the HPA01091DBVR pin-compatible with other TLV702xx variants in SOT-23-5 package?
Yes-the HPA01091DBVR shares identical SOT-23-5 (DBV) pinout with all TLV702xx DBV variants (e.g., TLV70212DBVR, TLV70228DBVR, TLV70233DBVR), including pin 1 (OUT), pin 2 (GND), pin 3 (IN), pin 4 (N/C), and pin 5 (EN). Output voltage is set internally; no external resistors are needed.
