Product details
Overview
LP3986TL-3030/NOPB from Texas Instruments is a dual micropower 150 mA ultra-low-dropout CMOS voltage regulator in an 8-bump DSBGA package, delivering 3.0 V and 3.0 V outputs with 60 mV dropout at full load, 40 µVrms output noise, and 200 µs fast turn-on - optimized for GSM/CDMA handset power rails and portable battery-powered systems.
For engineers reviewing the LP3986TL-3030/NOPB datasheet, LP3986TL-3030/NOPB pinout, LP3986TL-3030/NOPB application, or LP3986TL-3030/NOPB equivalent, this page provides verified regulator identity, dual-output LDO functionality, DSBGA-8 package mapping, thermal/overcurrent protection, and validated alternative options for space-constrained low-noise power management designs.
Technical Context
The LP3986TL-3030/NOPB integrates two independent LDO regulators sharing a common input (VIN) and ground, each with logic-controlled enable (EN1/EN2), internal 1.23 V bandgap reference, and dedicated BYPASS pin for noise reduction via 0.01 µF capacitor. It operates across 2.7 V to 6.0 V input and maintains regulation down to −40°C to +125°C junction temperature.
Its architecture features active pre-charge of the BYPASS node via a 70 µA internal current source, enabling 200 µs startup without compromising transient response. Crosstalk rejection exceeds −60 dB between outputs, and PSRR remains >50 dB at 10 kHz under 50 mA load - critical for RF-sensitive applications like cellular handsets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage (per regulator) | 3.0 V ±3.0% - matches baseband processor I/O and RF transceiver analog supply requirements |
| Max Output Current | 150 mA per regulator - sufficient for dual-rail subsystems including PMIC-independent audio codec and SIM interface |
| Dropout Voltage | 60 mV at 150 mA - enables operation down to 3.06 V input while maintaining 3.0 V output, extending battery runtime in Li-ion discharge tail |
| Quiescent Current | 115 µA typical (both ON), 1 nA shutdown - minimizes standby drain in always-on cellular modem states |
| Output Noise | 40 µVrms (10 Hz–100 kHz) - meets stringent noise floor requirements for RF front-end biasing and ADC reference supplies |
| PSRR | ≥50 dB at 10 kHz - suppresses switching noise from adjacent DC/DC converters in compact handheld PCB layouts |
| Enable Thresholds | VIL ≤ 0.4 V, VIH ≥ 1.4 V - compatible with 1.8 V and 3.3 V GPIO control without level-shifting |
Pinout & Package
LP3986TL-3030/NOPB uses an 8-bump DSBGA package (YZR0008), measuring 1.59 mm × 1.59 mm × 0.6 mm, with JEDEC-standard top-side bump layout and solder-ball pitch of 0.5 mm. The package is RoHS-compliant, SnAgCu ball finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT1 | First regulator output | 3.0 V regulated supply for primary digital subsystem (e.g., baseband processor core) |
| VOUT2 | Second regulator output | 3.0 V regulated supply for secondary analog/radio subsystem (e.g., PA bias or RF synthesizer) |
| VIN | Common input | Shared 2.7–6.0 V input rail - simplifies power sequencing and reduces input filtering components |
| EN1 | Enable for VOUT1 | Active-high logic control; ties directly to 1.8 V/3.3 V host processor GPIO |
| EN2 | Enable for VOUT2 | Independent active-high enable - supports staggered power-up of RF and baseband sections |
| BYPASS | Noise reduction node | Connects to 0.01 µF ceramic capacitor to reduce output noise without degrading load transient response |
| GND | Ground reference | Dual GND bumps (C2, C3) provide low-inductance return path for both regulators and minimize ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDOs | Enables separate power domains with individual enable control - eliminates need for two discrete regulators and saves >30% board area |
| Stable with 1 µF ceramic output cap | Reduces BOM count and cost vs. legacy LDOs requiring ≥10 µF tantalum; supports X7R/X5R dielectrics for wide-temp stability |
| Ultra-low ground current in shutdown | 1 nA max - preserves battery charge during deep sleep modes in cellular handsets and IoT edge nodes |
| Fast 200 µs turn-on with bypass pre-charge | Meets GSM burst timing requirements; avoids brownout during rapid RF power ramp-up |
| −60 dB crosstalk rejection | Prevents load transients on one output from disturbing sensitive analog supplies on the other - critical for mixed-signal SoC integration |
Applications
| GSM Cellular Handset Power | CDMA Baseband Subsystem |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL7407LPGQ | Single 7-channel high-side driver (not LDO); no voltage regulation, 40 V max VCC, open-drain outputs | Designed for relay/LED load switching, not precision low-noise power supply | Select only for load-driving applications - not a functional or pin-compatible replacement for LP3986TL-3030/NOPB |
| TPS79930YZPT | Single 200 mA LDO, 3.0 V fixed, 5-pin DSBGA, 170 mV dropout at 200 mA, 30 µVrms noise | Provides higher current but lacks dual-output capability and independent enables | Use when only one 3.0 V rail is needed and higher load current is required; requires second regulator for dual-rail systems |
Compared with LP3986TL-3030/NOPB, TPS79930YZPT offers lower noise and higher current but cannot replace the dual-output, independently enabled functionality - whereas TPL7407LPGQ serves a completely different circuit role and is not a voltage regulator at all.

FAQ
What output voltages does the LP3986TL-3030/NOPB deliver?
The LP3986TL-3030/NOPB delivers two fixed 3.0 V outputs (VOUT1 and VOUT2), each rated for up to 150 mA. Its part number suffix "3030" explicitly denotes the 3.0 V / 3.0 V configuration. Output voltage tolerance is ±3.0% over −40°C to +125°C, and regulation is maintained with input as low as 3.06 V due to its 60 mV dropout at full load.
Does the LP3986TL-3030/NOPB require external capacitors, and what values are recommended?
Yes, the LP3986TL-3030/NOPB requires external capacitors: a minimum 1 µF ceramic input capacitor (CIN), 1–22 µF ceramic output capacitor per rail (COUT), and a 0.01 µF ceramic bypass capacitor on the BYPASS pin. These values ensure stability, low noise (40 µVrms), and fast 200 µs turn-on - all validated per TI's SNVS142U datasheet for the LP3986TL-3030/NOPB.
How is power sequencing managed on the LP3986TL-3030/NOPB?
Power sequencing is managed via two independent logic-controlled enable inputs: EN1 controls VOUT1 and EN2 controls VOUT2. Both are active-high with VIH ≥ 1.4 V and VIL ≤ 0.4 V, compatible with 1.8 V and 3.3 V GPIOs. This allows staggered startup - for example, enabling VOUT1 first for baseband logic, then VOUT2 for RF circuitry - without external timing circuitry.
What thermal and protection features does the LP3986TL-3030/NOPB include?
The LP3986TL-3030/NOPB integrates overcurrent protection (600 mA short-circuit limit) and thermal shutdown with automatic recovery. Its DSBGA-8 package has θJA = 220°C/W, supporting up to 250 mW maximum power dissipation at 70°C ambient. Junction temperature is rated from −40°C to +125°C, and absolute maximum is 150°C - ensuring robust operation in handheld thermal environments.
Is the LP3986TL-3030/NOPB pin-compatible with other LP3986 variants?
Yes, all LP3986 variants - including LP3986TL-2518/NOPB, LP3986TL-2828/NOPB, and LP3986TL-3030/NOPB - share identical 8-bump DSBGA (YZR0008) packaging, pinout, and footprint. Only the output voltage combinations differ (e.g., 2.5 V/1.8 V, 2.8 V/2.8 V, 3.0 V/3.0 V). This enables drop-in replacement during design iteration or voltage optimization without PCB changes.
