Product details
Overview
LP3995ILD-3.0/NOPB from Texas Instruments is a micropower 150-mA CMOS low-dropout (LDO) voltage regulator in a 5-pin DSBGA package, delivering a fixed 3.0 V output with ±2% tolerance, 60 mV typical dropout at full load, and 25 µVRMS output noise (10 Hz–100 kHz). It powers RF/analog circuitry in space-constrained portable devices requiring fast enable/disable control and ultra-low quiescent current.
For engineers reviewing the LP3995ILD-3.0/NOPB datasheet, LP3995ILD-3.0/NOPB pinout, LP3995ILD-3.0/NOPB application, or LP3995ILD-3.0/NOPB equivalent, key selection criteria include its 30 µs turnon/175 µs turnoff timing, active discharge on shutdown, stability with 1-µF ceramic output capacitor, and −40°C to +125°C junction temperature range for industrial-grade reliability.
Technical Context
The LP3995ILD-3.0/NOPB integrates a precision bandgap reference, error amplifier, and PMOS pass transistor with internal thermal-overload and short-circuit protection. Its BYPASS pin connects directly to the reference node, enabling external 10 nF capacitor placement to suppress noise without degrading transient response.
Enable logic operates with VIH ≥ 0.9 V and VIL ≤ 0.4 V, driving an internal pull-down FET during disable to actively discharge the output capacitance. Ground current remains ≤1.5 µA when disabled, supporting battery-powered systems requiring near-zero standby power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% (±60 mV), ensuring stable bias for 3.0-V logic and analog ICs without external feedback. |
| Max Output Current | 150 mA continuous, sufficient for powering RF transceivers, sensor signal chains, or microcontroller cores. |
| Dropout Voltage | 60 mV typical at 150 mA load, enabling operation down to VIN = 3.06 V - critical for single-cell Li-ion or Li-poly battery systems. |
| Quiescent Current | 85–200 µA over load (0–150 mA), minimizing battery drain in always-on subsystems like real-time clocks or keep-alive RAM. |
| Output Noise | 25 µVRMS (10 Hz–100 kHz), low enough for sensitive analog front-ends (e.g., ADC references, RF synthesizers). |
| PSRR | 60 dB at 1 kHz, rejecting ripple from noisy switching supplies feeding the LDO input. |
| Enable Timing | 30 µs turnon / 175 µs turnoff (to 95%/5% of VOUT), enabling rapid power sequencing in multi-rail systems. |
Pinout & Package
LP3995ILD-3.0/NOPB uses a 5-pin DSBGA (YZR) package measuring 1.502 mm × 1.045 mm, with bottom-side thermal pad connected to GND for enhanced thermal performance in compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input supply connection | Accepts 2.5 V–6 V input; requires 1-µF ceramic capacitor placed ≤1 cm from pin for stability. |
| 2 (GND) | Power ground reference | Common return path for IN, OUT, EN, and BYPASS; thermal pad must be soldered to GND plane. |
| 3 (EN) | Logic-controlled enable input | Active-high: ≥0.9 V enables regulator; ≤0.4 V disables output and activates active discharge. |
| 4 (BYPASS) | Noise reduction node | Connects to internal bandgap reference; 10 nF capacitor reduces output noise and prevents startup overshoot. |
| 6 (OUT) | Regulated output terminal | Delivers 3.0 V to load; stable with ≥1-µF ceramic capacitor (X7R/Z5U/Y5V, ESR 5–500 mΩ). |
Key Features
| Feature | Design Value |
|---|---|
| Active discharge on shutdown | Internal FET pulls OUT to GND within 175 µs, preventing floating outputs and enabling safe power sequencing. |
| Stability with minimal capacitance | Guaranteed stable with only 1-µF ceramic output capacitor - reduces BOM count and board area vs. traditional LDOs. |
| Virtually zero disabled current | Typical 3 nA quiescent current when EN ≤ 0.4 V, extending battery life in sleep modes beyond standard micropower LDOs. |
| Low-noise reference architecture | BYPASS pin access to bandgap node allows 10 nF capacitor to cut output noise by >50% without affecting transient response. |
| Robust protection suite | Integrated thermal shutdown (160°C trip, 140°C hysteresis) and short-circuit current limiting (450 mA) prevent damage under fault conditions. |
Applications
| GSM/CDMA Handsets | Bluetooth Audio Modules |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL7407LDR | 300-mA output, 150 mV dropout at full load, no BYPASS pin, 40 µVRMS noise | Higher current capability but higher noise and no active discharge; suited for digital loads only | Select when >150 mA load current is required and noise sensitivity is low |
| MCP1703T-3002E/MB | 250-mA output, 600 mV dropout at full load, 1.8 µA quiescent current, no active discharge | Higher dropout limits use with low-VIN sources; slower 100 µs turnon; better for cost-sensitive non-battery apps | Select when board space allows larger SOT-23-5 and battery runtime is secondary to BOM cost |
Compared with TPL7407LDR and MCP1703T-3002E/MB, LP3995ILD-3.0/NOPB uniquely combines ultra-low noise (25 µVRMS), active output discharge, and sub-100 mV dropout in a 1.5 mm × 1.0 mm DSBGA - making it optimal for noise-critical, space-constrained, battery-powered RF/analog systems where fast, clean power sequencing is mandatory.

FAQ
What is the maximum input voltage rating for LP3995ILD-3.0/NOPB?
The absolute maximum input voltage for LP3995ILD-3.0/NOPB is 6.5 V. Operation above this level risks permanent damage. For reliable continuous operation, TI specifies a recommended maximum input of 6 V across the −40°C to +125°C junction temperature range. Exceeding 6 V may degrade long-term reliability even if below 6.5 V.
Does LP3995ILD-3.0/NOPB require an external bypass capacitor on the BYPASS pin?
Yes - LP3995ILD-3.0/NOPB requires a 10 nF ceramic capacitor between BYPASS and GND to achieve its specified 25 µVRMS output noise and prevent startup overshoot. Omitting this capacitor increases output noise by up to 2× and may cause transient instability during enable events.
Can LP3995ILD-3.0/NOPB operate without any load connected to the OUT pin?
Yes - LP3995ILD-3.0/NOPB remains stable and in regulation with zero load current. This no-load stability is confirmed across the full −40°C to +125°C temperature range and supports applications like CMOS RAM keep-alive circuits where output current drops to near-zero during sleep states.
What is the thermal resistance (RθJA) of the LP3995ILD-3.0/NOPB DSBGA package?
The junction-to-ambient thermal resistance (RθJA) for LP3995ILD-3.0/NOPB in its YZR DSBGA package is 181.2°C/W under JEDEC High-K board conditions. This value assumes proper PCB layout with thermal vias connecting the bottom thermal pad to internal GND planes - actual RθJA improves significantly with optimized copper area.
Is LP3995ILD-3.0/NOPB compatible with ceramic output capacitors smaller than 1 µF?
No - LP3995ILD-3.0/NOPB is explicitly designed and tested for stability with ≥1 µF ceramic output capacitance. Using capacitors below 1 µF violates the minimum stability requirement and may cause oscillation or poor transient response, especially under dynamic load conditions.
