Product details
Overview
LP8900TLX-3333/NOPB from Texas Instruments is a dual low-dropout linear regulator (LDO) delivering 200 mA per channel with ultra-low 6 µVRMS output noise and 75 dB PSRR at 1 kHz. It operates from 1.8 V to 5.5 V input, supports fixed 3.3 V outputs on both channels, and targets RF/analog power rails in space-constrained portable devices.
For engineers reviewing the LP8900TLX-3333/NOPB datasheet, LP8900TLX-3333/NOPB pinout, LP8900TLX-3333/NOPB application, or LP8900TLX-3333/NOPB equivalent, key selection criteria include dropout voltage (110 mV at 200 mA), thermal shutdown threshold (155°C), enable control thresholds (VIH = 1.2 V, VIL = 0.4 V), and DSBGA-6 package compatibility with 0402 ceramic capacitors.
Technical Context
The LP8900TLX-3333/NOPB integrates two independent LDO regulators sharing a common ground but featuring separate enable inputs (EN1, EN2) and output pins (OUT1, OUT2). Each channel uses a bandgap reference and error amplifier with internal 3-MΩ pulldown resistors on EN pins, enabling individual channel control without external pull-downs.
Its architecture delivers fast transient response (80 µs turn-on time, <1 mV line transient peak-to-peak deviation) and stable operation with 1-µF ceramic capacitors-enabled by optimized internal compensation and low-ESR capacitor tolerance (5–500 mΩ). The device is specified for –40°C to +125°C junction temperature and requires no noise bypass capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V per channel - eliminates external feedback network, reduces BOM count and layout area. |
| Max Output Current | 200 mA per channel - supports moderate-power RF ICs (e.g., transceivers, LNAs) and analog signal chains. |
| Output Noise | 6 µVRMS (10 Hz–100 kHz) - enables clean biasing of sensitive RF front-ends without added filtering. |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters in hybrid power architectures. |
| Dropout Voltage | 110 mV at 200 mA load - allows operation down to 3.41 V input for 3.3 V output, maximizing battery runtime. |
| Quiescent Current | 48 µA per regulator (typ.) - minimizes standby power in always-on subsystems like real-time clocks or sensor interfaces. |
| Enable Thresholds | VIH = 1.2 V, VIL = 0.4 V - compatible with 1.8 V/3.3 V logic families and enables direct MCU GPIO control. |
Pinout & Package
LP8900TLX-3333/NOPB is housed in a 6-pin DSBGA (YZR) package measuring 1.49 mm × 1.09 mm - optimized for ultra-compact PCB layouts in handheld and wearable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | EN1 | Active-high enable for Channel 1; internal 3-MΩ pulldown ensures default OFF state when unconnected. |
| A2 | OUT1 | Regulated 3.3 V output for Channel 1; requires local 1-µF ceramic capacitor to GND for stability. |
| B1 | GND | Common analog ground return for both regulators - must be connected to low-impedance system ground plane. |
| B2 | IN | Shared input supply (1.8–5.5 V); requires 1-µF ceramic capacitor within 1 cm for EMI suppression and stability. |
| C1 | EN2 | Active-high enable for Channel 2; independent of EN1 for flexible power sequencing in multi-rail systems. |
| C2 | OUT2 | Regulated 3.3 V output for Channel 2; electrically isolated from OUT1 except via shared GND and IN nodes. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-noise regulation | 6 µVRMS output noise without external bypass capacitor - reduces component count and board area vs. legacy LDOs. |
| Ceramic capacitor compatibility | Stable with 0402-case 1-µF X7R/X5R ceramics - enables sub-4 mm² total solution size including passives. |
| Independent dual-channel control | Separate EN1/EN2 pins allow staggered startup, dynamic power gating, or fault-isolated shutdown per rail. |
| High PSRR across frequency | 75 dB @ 1 kHz, 65 dB @ 10 kHz - maintains signal integrity in noisy mixed-signal environments with switching regulators. |
| Robust protection suite | Thermal shutdown (155°C), short-circuit current limit (600–900 mA), and reverse-voltage safe operation - enhances field reliability. |
Applications
| RF Transceiver Power Supply | High-Fidelity Audio Bias Rail |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL7407LADGQR | Single-channel 7-output high-side driver (not LDO); 3.3 V fixed output per channel, but lacks ultra-low-noise design and PSRR specs. | Designed for LED/relay driving, not analog/RF power - unsuitable for noise-sensitive loads. | Select only if driving discrete loads; not a functional substitute for LP8900TLX-3333/NOPB's low-noise regulation. |
| TPS7A2033PDQNR | Single-channel 3.3 V LDO (200 mA), 6.5 µVRMS noise, 70 dB PSRR @ 1 kHz - matches noise/PSRR but lacks dual-channel integration. | Requires two devices and extra PCB area to replicate dual-rail functionality; no independent enable per channel. | Use when single-rail simplicity is preferred; LP8900TLX-3333/NOPB saves space and enables per-rail sequencing. |
Compared with TPL7407LADGQR and TPS7A2033PDQNR, LP8900TLX-3333/NOPB uniquely combines dual 3.3 V rails, ultra-low noise, high PSRR, and independent enable control in a 1.49 mm × 1.09 mm DSBGA package - making it optimal for compact RF/analog systems where board area and power integrity are critical.

FAQ
What is the maximum input voltage rating for LP8900TLX-3333/NOPB?
The LP8900TLX-3333/NOPB has an absolute maximum input voltage of 6.5 V referenced to GND, but its recommended operating range is 1.8 V to 5.5 V. Exceeding 5.5 V may trigger thermal shutdown or reduce long-term reliability, even if within absolute ratings. Always maintain VIN ≤ 5.5 V in normal operation to ensure compliance with electrical characteristics and thermal specifications.
Does LP8900TLX-3333/NOPB require external capacitors, and what values are recommended?
Yes, LP8900TLX-3333/NOPB requires a 1-µF ceramic input capacitor (CIN) between IN and GND, and two 1-µF ceramic output capacitors (COUT1, COUT2) between each OUT pin and GND. X7R or X5R dielectrics are recommended; ESR must be 5–500 mΩ. Capacitors must be placed within 1 cm of respective pins and connected to a low-impedance ground plane to ensure stability and transient performance.
Can LP8900TLX-3333/NOPB operate with only one channel enabled?
Yes, LP8900TLX-3333/NOPB supports independent channel control: EN1 enables OUT1 and EN2 enables OUT2. Driving EN1 ≥1.2 V and EN2 ≤0.4 V powers only Channel 1, drawing ~48 µA quiescent current. This enables flexible power sequencing, dynamic rail disabling, and reduced system standby power - confirmed in Electrical Characteristics and Pin Functions sections of the datasheet.
What is the thermal shutdown behavior of LP8900TLX-3333/NOPB?
LP8900TLX-3333/NOPB activates thermal shutdown at 155°C junction temperature, halting output regulation and reducing power dissipation. It features 15°C hysteresis, so regulation resumes only after junction temperature falls below 140°C. This protects against permanent damage during sustained overload or poor PCB thermal design, and is fully characterized across –40°C to +125°C operating range.
Is LP8900TLX-3333/NOPB compatible with lead-free reflow processes?
Yes, LP8900TLX-3333/NOPB uses a DSBGA-6 (YZR) package qualified for standard lead-free reflow profiles per JEDEC J-STD-020. Its maximum peak reflow temperature is 260°C, and it complies with IPC/JEDEC standard moisture sensitivity level (MSL) 1 - meaning floor life is unlimited when stored at ≤30°C/60% RH. Refer to TI Application Note AN-1112 for DSBGA-specific solder paste and reflow guidance.
