Product details
Overview
LP3995ITLX-3.0/NOPB from Texas Instruments is a micropower 150-mA CMOS low-dropout linear 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 - designed for RF/analog power rails in space-constrained portable devices.
For engineers reviewing the LP3995ITLX-3.0/NOPB datasheet, LP3995ITLX-3.0/NOPB pinout, LP3995ITLX-3.0/NOPB application, or LP3995ITLX-3.0/NOPB equivalent, key selection criteria include fast enable/disable timing (30 µs turnon / 175 µs turnoff), active output discharge, stability with 1-µF ceramic COUT, and operation across −40°C to +125°C junction temperature.
Technical Context
The LP3995ITLX-3.0/NOPB integrates a precision bandgap reference, error amplifier, and PMOS pass transistor with internal thermal shutdown 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 control uses logic-level thresholds (VIL ≤ 0.4 V, VIH ≥ 0.9 V) and activates an internal pull-down FET during disable to rapidly discharge COUT. Quiescent current drops to 3 nA in shutdown, while ground current remains stable from no-load to 150 mA across input voltages of 2.5 V–6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% (±60 mV) over −40°C to +125°C; meets tight analog/RF supply requirements. |
| Max Output Current | 150 mA continuous; supports baseband processors, Bluetooth radios, and sensor signal chains. |
| Dropout Voltage | 60 mV typical at 150 mA; enables operation down to 3.06 V input, extending battery runtime in single-cell Li-ion systems. |
| Output Noise | 25 µVRMS (10 Hz–100 kHz); low enough for sensitive ADCs, VCOs, and RF front-ends without additional filtering. |
| PSRR | 60 dB at 1 kHz; rejects ripple from switching converters feeding intermediate supply rails. |
| Enable Timing | 30 µs turnon / 175 µs turnoff; supports rapid power sequencing in multi-rail portable systems. |
| Operating Input Range | 2.5 V to 6 V; compatible with Li-ion, Li-poly, and 3.3 V/5 V system rails. |
Pinout & Package
LP3995ITLX-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. Pin numbering follows top-view layout: A3 = BYPASS, C3 = IN, A1 = EN, B2 = GND, C1 = OUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (C3) | Input voltage supply | Accepts 2.5–6 V; requires 1-µF ceramic capacitor within 1 cm of pin for stability. |
| GND (B2) | Power ground reference | Common return for IN, OUT, EN, and BYPASS; connects to PCB ground plane. |
| EN (A1) | Logic-enable control input | Active-high: ≥0.9 V enables regulator; ≤0.4 V disables output and activates active discharge. |
| BYPASS (A3) | Reference noise filter node | Connects to 10 nF NPO/COG capacitor to reduce output noise and prevent startup overshoot. |
| OUT (C1) | Regulated output voltage | Delivers 3.0 V ±2% to load; stable with 1-µF ceramic capacitor (X7R/Y5V/Z5U, ESR 5–500 mΩ). |
Key Features
| Feature | Design Value |
|---|---|
| Virtually zero quiescent current in shutdown | 3 nA typical IQ when EN ≤ 0.4 V - eliminates standby drain in battery-powered sleep modes. |
| Active output discharge on disable | Internal FET pulls OUT to GND within 175 µs - prevents floating voltage and ensures clean reset sequencing. |
| Stable with 1-µF ceramic output capacitor | No minimum ESR requirement; enables smallest possible footprint and lowest BOM cost vs. tantalum alternatives. |
| Low-noise bandgap reference with bypass | 10 nF capacitor on BYPASS reduces output noise by >50% without slowing transient response. |
| Thermal and short-circuit protection | Shuts down at ~160°C junction temp; auto-restarts at ~140°C - protects against sustained overload or poor heatsinking. |
Applications
| GSM/CDMA Handsets | Bluetooth Audio Modules |
|---|---|
|
Use Scenario: Powering RF transceivers and baseband ICs in dual-mode cellular handsets with tight noise and size constraints. IC Role / Device Role / Timing Role: Primary 3.0 V LDO for GSM PA bias and CDMA VCO supply, sequenced via baseband processor EN signal.

Use Scenario: Regulating 3.0 V for LoRaWAN/Wi-Fi MCUs and environmental sensors in sealed industrial gateways. IC Role / Device Role / Timing Role: Robust local supply with thermal protection, operating continuously across −40°C to +85°C ambient. Use Value: 125°C max junction rating and integrated TSD ensure reliability in unventilated enclosures; DSBGA footprint saves PCB area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL720F30DRVR | Same 3.0 V output, 200 mA rating, but higher 120 µVRMS noise and no BYPASS pin. | Lacks active discharge and noise-bypass capability; less suitable for RF-sensitive or fast-sequencing designs. | Choose if higher current headroom is needed and noise/sequencing are secondary. |
| MCP1700T-3002E/MB | 3.0 V, 250 mA, 6 µA quiescent current (vs. 150 µA active), but 200 µs turnoff and no active discharge. | Higher IQ in active mode; slower disable limits use in aggressive power-gating schemes. | Prefer for cost-sensitive, non-RF applications where 6 µA shutdown current suffices. |
Compared with TPL720F30DRVR and MCP1700T-3002E/MB, LP3995ITLX-3.0/NOPB uniquely combines ultra-low noise (25 µVRMS), active output discharge, and sub-200 µs turnoff - making it optimal for RF, audio, and battery-constrained portable systems requiring clean, fast, and reliable regulation.

FAQ
What is the maximum input voltage for LP3995ITLX-3.0/NOPB?
The absolute maximum input voltage for LP3995ITLX-3.0/NOPB is 6.5 V, but the recommended operating range is 2.5 V to 6 V per the datasheet. Exceeding 6.5 V risks permanent damage. For reliable operation with margin, keep VIN ≤ 6.0 V under all conditions including transients.
Does LP3995ITLX-3.0/NOPB require an external bypass capacitor?
Yes - LP3995ITLX-3.0/NOPB requires a 10 nF ceramic capacitor (NPO/COG preferred) between the BYPASS pin and GND. This capacitor reduces output noise by stabilizing the internal bandgap reference and prevents output overshoot during startup. Omitting it increases noise and may cause instability under dynamic load.
Can LP3995ITLX-3.0/NOPB operate without a load?
Yes - LP3995ITLX-3.0/NOPB remains stable and in regulation with zero load current. This no-load stability is confirmed in Section 9.2.2.4 of the datasheet and is essential for applications like CMOS RAM keep-alive circuits or standby power domains where the output may be disconnected intermittently.
What is the thermal shutdown behavior of LP3995ITLX-3.0/NOPB?
LP3995ITLX-3.0/NOPB activates thermal shutdown at approximately 160°C junction temperature and auto-restarts when cooling to ~140°C. This hysteresis prevents oscillation. The device is not intended for continuous thermal cycling; proper PCB copper area and thermal vias are required to avoid repeated trips in high-power dissipation scenarios.
Is LP3995ITLX-3.0/NOPB pin-compatible with other LP3995 variants?
Yes - all LP3995 variants in the YZR (DSBGA) package share identical 5-pin pinout and footprint, including LP3995ITLX-1.5/NOPB, LP3995ITLX-2.8/NOPB, and LP3995ITLX-3.0/NOPB. Only the output voltage differs; no PCB changes are needed when swapping fixed-voltage versions within the same package.
