Product details
Overview
LP5907YKGR-2.8 from Texas Instruments is a 250mA, low-noise, low-IQ linear regulator delivering a fixed 2.8V output with ±2% tolerance, 12μA quiescent current (enabled), 120mV typical dropout at 250mA, and <6.5µVRMS output noise - designed for RF and analog power rails in space-constrained portable electronics.
For engineers reviewing the LP5907YKGR-2.8 datasheet, LP5907YKGR-2.8 pinout, LP5907YKGR-2.8 application, or LP5907YKGR-2.8 equivalent, this page delivers verified package mapping (DSBGA-4 YKG), confirmed pin functions (IN/OUT/EN/GND), thermal protection behavior, remote capacitor placement capability, and real-world PSRR (82dB @ 1kHz) and load regulation performance.
Technical Context
The LP5907YKGR-2.8 employs a proprietary low-noise reference architecture with integrated RC filtering (–3dB at ~0.1Hz) to achieve <6.5µVRMS noise without an external bypass capacitor. Its enable circuit includes a 1MΩ internal pulldown resistor and VIH/VIL thresholds (1.2V/0.4V) referenced to VIN.
It supports remote output capacitor placement up to 10cm from the device due to inherent stability with only 1µF ceramic COUT, and integrates thermal shutdown (160°C trip, 15°C hysteresis) and short-circuit current limiting (250–500mA). The DSBGA-4 (YKG) package uses a bottom-side thermal pad connected to GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8V ±2% - ensures stable bias for 2.8V logic, RF front-end ICs, and precision analog sensors without external feedback. |
| Max Output Current | 250mA - sufficient for powering baseband processors, camera modules, or multi-channel ADCs in compact devices. |
| Quiescent Current | 12μA (enabled) - enables >1-year battery life in always-on sensor nodes or standby circuits. |
| Dropout Voltage | 120mV (typical, 250mA, DSBGA) - allows operation from 3.0V input while maintaining 2.8V output under full load. |
| Output Noise | <6.5µVRMS (10Hz–100kHz) - meets stringent spectral purity requirements for GSM/UMTS/LTE RF receivers and high-SNR audio codecs. |
| PSRR | 82dB @ 1kHz - suppresses switching noise from adjacent DC/DC converters feeding noisy system rails. |
| Input Voltage Range | 2.2V to 5.5V - compatible with single-cell Li-ion (2.7–4.2V), Li-polymer, or 3.3V/5V system supplies. |
| Operating Temperature | –40°C to +125°C (junction) - qualified for automotive infotainment, industrial handhelds, and outdoor IoT edge nodes. |
Pinout & Package
LP5907YKGR-2.8 is packaged in a 0.685mm × 0.685mm, 4-ball DSBGA (YKG) with bottom-side thermal pad connected to GND. Pinout follows standard DSBGA top-view layout: A1 = IN, A2 = OUT, B1 = EN, B2 = GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (IN) | Input voltage supply | Accepts 2.2–5.5V; requires ≥1µF ceramic capacitor placed ≤1cm from pin to ensure transient response and stability. |
| A2 (OUT) | Regulated output | Delivers fixed 2.8V; supports remote capacitor placement up to 10cm; internal 230Ω pulldown discharges VOUT during shutdown. |
| B1 (EN) | Enable control input | Active-high logic; VIH ≥1.2V, VIL ≤0.4V; internal 1MΩ pulldown holds regulator off by default; no external pull-down needed. |
| B2 (GND) | Power ground | Common return path; thermal pad (underside) must be soldered to PCB GND plane for thermal performance and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| No external noise bypass capacitor required | Integrated RC-filtered reference reduces output noise to <6.5µVRMS without added BOM cost or board area. |
| Stable with 1µF input and output ceramics | Eliminates need for larger or specialized capacitors - simplifies sourcing and reduces footprint in ultra-thin mobile designs. |
| Remote output capacitor placement | Enables routing flexibility: 1µF COUT may be placed up to 10cm from device, easing layout around dense RF sections or connectors. |
| Thermal and short-circuit protection | Auto-shutdown at 160°C junction temperature with 15°C hysteresis; current limit prevents damage during output faults or hot-plug events. |
| Ultra-low quiescent current | 12μA enabled current extends battery runtime in always-on applications such as BLE beacons or environmental monitors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL720F12-2.8 | 200mA max output, 15μA IQ, 70mV dropout (250mA), same DSBGA-4 package but lower current rating and higher noise (9µVRMS). | Suitable for lower-current analog rails (e.g., op-amp bias) but not for 250mA RF loads. | Select if board space and thermal constraints dominate over current capability and noise floor. |
| TPS7A2028PDBVR | 300mA max output, 6.5μA IQ, 130mV dropout (250mA), SOT-23-5 package, identical 2.8V output and <6.5µVRMS noise. | Requires different PCB footprint and has no thermal pad; better suited for non-RF, cost-sensitive industrial designs. | Choose when higher current headroom and lowest possible IQ are critical, and SOT-23 layout is acceptable. |
Compared with TPL720F12-2.8, LP5907YKGR-2.8 delivers 25% more output current and lower noise for RF-sensitive applications; versus TPS7A2028PDBVR, it offers superior thermal performance via DSBGA thermal pad but requires tighter layout control for remote capacitor placement.

FAQ
What is the maximum output current supported by the LP5907YKGR-2.8?
The LP5907YKGR-2.8 supports a continuous output current of up to 250mA, as specified in the absolute maximum ratings and electrical characteristics tables. This rating applies across the full operating temperature range (–40°C to +125°C junction) and is validated for the YKG DSBGA package with proper PCB thermal design. Exceeding this current may trigger thermal shutdown or degrade output regulation.
Does the LP5907YKGR-2.8 require an external noise bypass capacitor?
No, the LP5907YKGR-2.8 does not require an external noise bypass capacitor. Its internal low-noise reference includes an integrated RC filter (–3dB at ~0.1Hz), enabling <6.5µVRMS output noise with only a 1µF ceramic output capacitor. This eliminates BOM cost, board area, and layout complexity associated with traditional LDO bypass networks.
Can the output capacitor of the LP5907YKGR-2.8 be placed remotely from the device?
Yes, the LP5907YKGR-2.8 supports remote output capacitor placement up to 10cm from the device, as confirmed in the functional description and application section. This capability stems from its inherent stability with a minimum 1µF ceramic COUT, allowing flexible layout around RF-sensitive areas or mechanical obstructions without compromising transient response or noise performance.
What is the dropout voltage of the LP5907YKGR-2.8 at full load?
The dropout voltage of the LP5907YKGR-2.8 is 120mV (typical) at 250mA load current for the YKG DSBGA package, as specified in the Electrical Characteristics table. This value ensures reliable 2.8V output regulation from a 3.0V input supply under worst-case conditions, supporting efficient operation in battery-powered systems with declining cell voltage.
How does the enable (EN) pin of the LP5907YKGR-2.8 behave during power-up?
The EN pin of the LP5907YKGR-2.8 features an internal 1MΩ pulldown resistor to GND, ensuring the device remains disabled until a valid high-level signal (≥1.2V) is applied. During power-up, if EN is left floating or weakly driven, the regulator stays off by default - preventing uncontrolled output activation and protecting downstream circuitry from unintended bias conditions.
