Product details
Overview
LP5900TLX-2.2/NOPB from Texas Instruments is a 150-mA ultra-low-noise LDO regulator designed for RF and analog circuits, delivering 2.2 V output with ±2% tolerance, 6.5 μVRMS output noise, 75 dB PSRR at 1 kHz, and 80 mV typical dropout voltage. It operates from 2.5 V to 5.5 V input and supports stable regulation with only 0.47-μF ceramic input/output capacitors-no noise bypass capacitor required-making it ideal for space-constrained cellular RF front-ends.
For engineers reviewing the LP5900TLX-2.2/NOPB datasheet, LP5900TLX-2.2/NOPB pinout, LP5900TLX-2.2/NOPB application, or LP5900TLX-2.2/NOPB equivalent, key selection criteria include low-noise power delivery for sensitive RF ICs, minimal external component count, thermal shutdown behavior at 160°C, enable-controlled sequencing in portable systems, and compatibility with DSBGA-4 (YZR) packaging for ultra-thin mobile designs.
Technical Context
The LP5900TLX-2.2/NOPB employs an internal low-pass RC filter on its reference voltage path to suppress intrinsic noise, eliminating need for external bypass capacitance. Its enable logic features a 1-MΩ internal pull-down resistor and defined VIH/VIL thresholds (1.2 V / 0.4 V), ensuring robust digital control across −40°C to 125°C junction temperature range.
Stability is guaranteed with 0.47-μF X7R/X5R ceramic capacitors (ESR 5–500 mΩ) on both input and output; no minimum load requirement exists. Thermal-overload protection activates at ~160°C with 20°C hysteresis, and dropout performance remains specified down to 150 mA load at full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.2 V ±2% - ensures precise biasing for RF transceivers and analog baseband ICs without trimming. |
| Max Output Current | 150 mA - sufficient for powering single RF power amplifiers or low-power ADC/DAC stages. |
| Output Noise | 6.5 μVRMS (10 Hz–100 kHz) - enables clean supply for LNAs and VCOs without added filtering. |
| PSRR @ 1 kHz | 75 dB - rejects switching noise from PMICs or DC/DC converters feeding the LDO input. |
| Dropout Voltage | 80 mV typ. @ 150 mA - allows operation from 2.5 V input while maintaining 2.2 V output, critical for battery-powered devices. |
| Quiescent Current | 25 μA enabled / <1 μA disabled - extends battery life in always-on RF monitoring or sleep-mode subsystems. |
| Enable Thresholds | VIH = 1.2 V, VIL = 0.4 V - compatible with 1.8 V and 3.3 V GPIOs without level-shifting. |
Pinout & Package
LP5900TLX-2.2/NOPB is packaged in a 4-pin DSBGA (YZR) with 1.108 mm × 1.083 mm body size and exposed thermal pad on bottom. The package requires soldering to PCB ground plane via thermal vias for optimal thermal performance (RθJB = 35.6°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (B2) | Regulated output | Delivers stable 2.2 V to load; must connect 0.47-μF ceramic cap within 1 cm to analog ground. |
| GND (B1) | Power ground | Common return for input, output, and internal circuitry; ties to PCB ground plane and thermal pad. |
| IN (A2) | Input supply | Accepts 2.5–5.5 V; requires 0.47-μF ceramic decoupling cap near pin to suppress high-frequency ripple. |
| EN (A1) | Logic enable | Active-high control: ≥1.2 V enables regulator; ≤0.4 V disables output and reduces IQ to <1 μA. |
Key Features
| Feature | Design Value |
|---|---|
| No-bypass-capacitor architecture | Integrated RC-filtered reference eliminates need for external 10-nF noise capacitor, reducing BOM count and board area. |
| Ultra-low-noise regulation | 6.5 μVRMS output noise enables direct powering of RF receivers without degrading SNR or phase noise. |
| Thermal shutdown with hysteresis | Triggers at 160°C and re-enables at ~140°C, preventing permanent damage during sustained overload or poor heatsinking. |
| Zero-load stability | Maintains regulation with no external load - essential for standby modes where downstream circuits may be powered off. |
| Low-ESR capacitor support | Stable with 5–500 mΩ ESR ceramic caps; avoids instability risks associated with high-ESR tantalum or electrolytic types. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL720F12-DBVR | 120-mA output, 1.2 V fixed, 12 μVRMS noise, requires 1-μF output cap | Lower current and different output voltage; higher noise than LP5900TLX-2.2/NOPB | Select when 1.2 V bias is needed and 150 mA headroom is not required. |
| TPS7A2022PDQNR | 300-mA output, 2.2 V fixed, 7 μVRMS noise, stable with 1-μF cap, 65 dB PSRR @ 1 kHz | Higher current capability but lower PSRR and larger WSON-6 package vs. DSBGA-4 | Choose for higher load margin or if board layout accommodates larger footprint and thermal pad routing. |
Compared with TPL720F12-DBVR and TPS7A2022PDQNR, LP5900TLX-2.2/NOPB uniquely balances ultra-low noise (6.5 μVRMS), high PSRR (75 dB), minimal 0.47-μF capacitor support, and ultra-compact DSBGA-4 packaging-making it optimal for noise-critical, space-constrained RF analog rails where 150 mA is sufficient.

FAQ
What is the minimum input voltage required for LP5900TLX-2.2/NOPB to regulate 2.2 V output?
The LP5900TLX-2.2/NOPB requires a minimum input voltage of 2.5 V to operate, but to maintain regulation at full 150 mA load, VIN must be ≥ VOUT + VDO = 2.2 V + 0.08 V = 2.28 V. Per datasheet Section 6.3, recommended minimum VIN is 2.5 V across −40°C to 125°C junction temperature range. Below 2.5 V, internal circuitry is not fully functional.
Does LP5900TLX-2.2/NOPB require an external noise bypass capacitor?
No, LP5900TLX-2.2/NOPB does not require an external noise bypass capacitor. Its internal reference voltage path includes a first-order low-pass RC filter that reduces intrinsic noise before reaching the output buffer-enabling 6.5 μVRMS noise performance with only 0.47-μF input and output ceramic capacitors, as confirmed in Sections 1, 7.3.3, and 8.2 of the SNVS358R datasheet.
What is the thermal shutdown behavior of LP5900TLX-2.2/NOPB?
LP5900TLX-2.2/NOPB activates thermal shutdown at approximately 160°C junction temperature and re-enables at ~140°C due to 20°C hysteresis. This cycling protects the device during sustained overload or inadequate PCB heatsinking. The thermal pad must be connected to PCB ground via thermal vias to achieve RθJB = 35.6°C/W and avoid premature trip under 150 mA load at elevated ambient temperatures.
Can LP5900TLX-2.2/NOPB operate with no load connected to the OUT pin?
Yes, LP5900TLX-2.2/NOPB remains stable and in regulation with zero load current. Section 7.3.1 explicitly states "No-Load Stability": the device maintains output voltage regulation without requiring a minimum load, which is essential for power-gating scenarios in portable systems where downstream circuits may be disabled.
What capacitor types and values are validated for use with LP5900TLX-2.2/NOPB?
LP5900TLX-2.2/NOPB is validated for stable operation with 0.47-μF ceramic capacitors (X5R or X7R dielectric) on both IN and OUT pins, with ESR between 5 mΩ and 500 mΩ. TI recommends X7R for superior temperature stability (±15% over −40°C to 125°C); Y5V/Z5U types are discouraged due to >50% capacitance loss at temperature extremes, per Section 8.2.2.2.3.
