Product details
Overview
LP5907A28YKMR from Texas Instruments is a 250mA, low-noise, low-IQ LDO regulator delivering a fixed 2.8V output with ±2% tolerance, 12μA quiescent current (enabled), <6.5µVRMS output noise, and 82dB PSRR at 1kHz - designed for powering RF and analog circuits in space-constrained portable devices.
For engineers reviewing the LP5907A28YKMR datasheet, LP5907A28YKMR pinout, LP5907A28YKMR application, or LP5907A28YKMR equivalent, key selection criteria include dropout voltage (120mV typ. @250mA), remote output capacitor support (up to 10cm), thermal shutdown (160°C), and compatibility with 1µF ceramic input/output capacitors without bypass requirements.
Technical Context
The LP5907A28YKMR uses an innovative internal RC-filtered reference architecture to achieve ultra-low noise without external bypass capacitors. Its enable logic includes a 1MΩ internal pulldown and defined VIH/VIL thresholds (1.2V/0.4V) for reliable sequencing control.
It supports remote output capacitor placement up to 10cm via stable loop compensation, and integrates automatic output discharge (230Ω pulldown) during disable. Thermal protection activates at 160°C with 15°C hysteresis, and operation is specified from –40°C to 125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8V ±2% - ensures precise biasing for RF transceivers and ADCs without external feedback. |
| Max Output Current | 250mA - sufficient for powering multiple low-power analog/RF blocks (e.g., VCOs, LNAs, sensor interfaces). |
| Quiescent Current | 12μA (enabled) - enables multi-week battery life in always-on sensor or IoT endpoint applications. |
| Output Noise | <6.5µVRMS (10Hz–100kHz) - meets stringent spectral purity requirements for GSM/WCDMA/LTE front-end power rails. |
| PSRR | 82dB at 1kHz - suppresses switching noise from adjacent DC/DC converters feeding mixed-signal SoCs. |
| Dropout Voltage | 120mV typical @250mA (DSBGA) - allows operation down to 2.92V input while maintaining 2.8V output under full load. |
| Capacitor Support | Stable with 1µF ceramic input/output - eliminates BOM cost and board area for bulk or bypass caps; enables ultra-compact layout. |
Pinout & Package
LP5907A28YKMR is packaged in a 4-pin DSBGA (YKM) measuring 0.685mm × 0.685mm with bottom-side solder balls. This ultra-small package targets high-density mobile PCBs where footprint and thermal performance are critical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (IN) | Input voltage supply | Accepts 2.2V–5.5V; requires ≥1µF ceramic cap within 1cm for stability and transient response. |
| A2 (OUT) | Regulated output | Delivers fixed 2.8V; supports remote capacitor placement up to 10cm due to robust loop compensation. |
| B1 (EN) | Enable control input | Active-high; 1MΩ internal pulldown ensures default-off state; VIH = 1.2V min, VIL = 0.4V max. |
| B2 (GND) | Ground reference | Common return path for input, output, and enable; must connect to low-impedance analog ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Noise-bypass capacitor elimination | Internal RC-filtered reference achieves <6.5µVRMS noise without external bypass cap - reduces BOM count and layout complexity. |
| Remote output capacitor support | Stable operation with 1µF ceramic cap placed up to 10cm from OUT pin - enables flexible partitioning of power and signal sections on dense PCBs. |
| Automatic output discharge | 230Ω internal pulldown discharges VOUT when EN is low - prevents floating rail issues and ensures clean power-down sequencing. |
| Ultra-low quiescent current | 12μA enabled IQ - extends battery runtime in always-on wearable or remote sensor nodes without sacrificing regulation accuracy. |
| Thermal overload protection | 160°C shutdown with 15°C hysteresis - safeguards device during sustained overloads or poor heatsinking without requiring external circuitry. |

FAQ
What is the maximum output current supported by the LP5907A28YKMR?
The LP5907A28YKMR delivers up to 250mA of continuous output current while maintaining regulation and thermal safety. This rating applies across the full operating temperature range (–40°C to 125°C junction) and is validated for the YKM DSBGA package per TI's datasheet SNVS798Q. Exceeding this current may trigger thermal shutdown or degrade output accuracy.
Does the LP5907A28YKMR require an external noise bypass capacitor?
No, the LP5907A28YKMR does not require an external noise bypass capacitor. Its internal RC-filtered reference architecture achieves <6.5µVRMS output noise (10Hz–100kHz) inherently. This eliminates a common BOM item and simplifies layout - confirmed in Section 6.3.2 and Figure 5-17 of the official datasheet.
What is the recommended input and output capacitance for the LP5907A28YKMR?
The LP5907A28YKMR is stable with a minimum 1µF ceramic capacitor on both input and output pins. The datasheet specifies 0.7µF as the absolute minimum under worst-case tolerance/temperature conditions, but 1µF is the design target. X7R dielectrics are recommended; ESR must be between 5mΩ and 500mΩ.
Can the output capacitor of the LP5907A28YKMR be placed remotely from the IC?
Yes - the LP5907A28YKMR supports remote output capacitor placement up to 10cm from the OUT pin, enabled by its optimized internal compensation. This feature is explicitly documented in Sections 6.3.4 and 7.1 of the datasheet and verified across temperature and load conditions, facilitating flexible PCB partitioning in RF-sensitive layouts.
What is the enable logic behavior of the LP5907A28YKMR?
The LP5907A28YKMR EN pin is active-high with an internal 1MΩ pulldown resistor, ensuring default-off operation. It enables fully when pulled above 1.2V (VIH) and disables fully below 0.4V (VIL). During disable, the 230Ω internal pulldown discharges the output, preventing residual charge - details are in Table 4-1 and Section 6.3.1.
