Product details
Overview
NCP160BFCS514T2G from onsemi is a 250 mA ultra-low-noise, high-PSRR LDO regulator with fixed 5.14 V output, 80 mV dropout at 250 mA, ±2% output accuracy over load/temperature, and 10 µVRMS noise (10 Hz–100 kHz). It targets RF and analog power rails in battery-powered wireless devices requiring clean, stable voltage under dynamic load.
For engineers reviewing the NCP160BFCS514T2G datasheet, pinout, applications, or equivalent options, key selection criteria include its 5.14 V fixed output, WLCSP4 0.64 mm × 0.64 mm package, active-discharge-free operation (B-suffix), 98 dB PSRR at 1 kHz, and compatibility with 1 µF ceramic input/output capacitors.
Technical Context
The NCP160BFCS514T2G uses a PMOS pass transistor architecture enabling low dropout and inherent reverse-current protection. Its bandgap reference and integrated soft-start ensure stable startup without output overshoot, while thermal shutdown (160°C trip, 140°C reset) and current limiting (700 mA typ.) provide robust fault handling.
Unlike A-suffix variants, the B-suffix denotes absence of active output discharge - EN pin assertion disables regulation but leaves VOUT floating. The device operates across 1.9 V–5.5 V input range and maintains 98 dB PSRR at 1 kHz and 10 µVRMS noise, making it suitable for sensitive RF front-end biasing where supply ripple and broadband noise must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.14 V ±2% - enables direct powering of 5.1 V logic or analog circuits without external feedback. |
| Max Output Current | 250 mA - supports moderate-power RF ICs, camera sensors, or baseband processors in compact portable systems. |
| Dropout Voltage | 80 mV at 250 mA - allows operation from 5.22 V input, preserving headroom in 5.5 V rail-constrained designs. |
| PSRR | 98 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding shared input rails. |
| Output Noise | 10 µVRMS (10 Hz–100 kHz) - meets stringent noise requirements for RF transceivers and high-resolution ADC/DAC references. |
| Quiescent Current | 18 µA typ. - extends battery life in always-on sensor or IoT edge nodes with intermittent RF activity. |
| Enable Threshold | VENH = 1.2 V, VENL = 0.4 V - compatible with standard GPIOs and supports simple microcontroller-controlled power sequencing. |
Pinout & Package
Package: WLCSP4 (Case 567JZ), 0.64 mm × 0.64 mm × 0.33 mm, Pb-free, RoHS-compliant. Exposed pad (EPAD) tied to GND for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | IN | Input voltage supply pin - accepts 1.9 V–5.5 V; requires 1 µF ceramic capacitor placed adjacent to minimize trace inductance. |
| A2 | OUT | Regulated 5.14 V output - bypassed with 1 µF ceramic capacitor; no ESR requirement but <2 Ω recommended for optimal transient response. |
| B1 | EN | Chip enable control - logic-high (>1.2 V) enables regulation; logic-low (<0.4 V) disables output (no active discharge). |
| B2 | GND | Common ground reference - connects to system ground plane; EPAD must also be soldered to GND for thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise | 10 µVRMS (10 Hz–100 kHz) - preserves signal integrity in RF receiver LNAs and PLL VCO bias supplies. |
| High PSRR | 98 dB at 1 kHz - rejects ripple from noisy switchers, reducing need for additional filtering stages. |
| Low quiescent current | 18 µA typ. - enables multi-week standby in coin-cell-powered Bluetooth LE or NB-IoT modules. |
| Stable with 1 µF ceramics | No minimum ESR requirement - simplifies BOM by eliminating tantalum or polymer capacitors. |
| Thermal protection | 160°C shutdown / 140°C reset - prevents permanent damage during sustained overload or poor PCB heatsinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCP160AFCS514T2G | Same specs but includes active output discharge (280 Ω pull-down when disabled) | Required where rapid VOUT discharge is needed for system-level power sequencing or safety | Select NCP160AFCS514T2G only if active discharge is explicitly required; NCP160BFCS514T2G avoids unintended discharge loading. |
| TPL7407LPGEDR | 7-channel 250 mA LDO, 5.1 V output, 12 µVRMS noise, no EN pin, different pinout | Multi-rail systems needing consolidated regulation; lacks enable control and active discharge | Choose TPL7407LPGEDR for space-constrained multi-supply designs; NCP160BFCS514T2G preferred for single-rail, GPIO-controllable applications. |
Compared with NCP160AFCS514T2G, the NCP160BFCS514T2G eliminates active discharge to reduce standby leakage and simplify sequencing, while retaining identical noise, PSRR, and accuracy. Against TPL7407LPGEDR, it offers discrete enable control and smaller footprint per channel but requires separate regulation per rail.

FAQ
What is the output voltage tolerance of the NCP160BFCS514T2G across temperature and load?
The NCP160BFCS514T2G guarantees ±2% output voltage accuracy over the full operating junction temperature range (−40°C to +125°C) and full load range (0 mA to 250 mA). This is confirmed in the Electrical Characteristics table (page 4 of datasheet), where VOUT is specified as −2% to +2% under all test conditions including worst-case VIN and IOUT combinations.
Does the NCP160BFCS514T2G include active output discharge functionality?
No, the NCP160BFCS514T2G does not include active output discharge. The "B" suffix explicitly denotes non-active-discharge version. When EN is pulled low, the pass transistor turns off and VOUT floats - unlike the "A"-suffix variants (e.g., NCP160AFCS514T2G) which pull VOUT to GND via a 280 Ω internal resistor. This behavior is documented in the Applications Information section (page 14).
What is the minimum input voltage required for the NCP160BFCS514T2G to regulate at full 250 mA load?
The minimum input voltage is 5.22 V - calculated as VOUT + VDO = 5.14 V + 80 mV (typical dropout at 250 mA). At higher temperatures or worst-case process corners, dropout may reach 105 mV (per datasheet Table, page 4), so 5.245 V ensures margin. Input below this causes dropout mode and unregulated output.
Can the NCP160BFCS514T2G be used with ceramic capacitors smaller than 1 µF?
The NCP160BFCS514T2G is characterized and guaranteed stable with ≥1 µF X5R/X7R ceramic capacitors. While Figure 37 (page 11) shows stability down to ~0.7 µF effective capacitance, derating due to DC bias (especially in 0201 packages) means 1 µF is the minimum recommended value. Using <1 µF risks instability or degraded transient response.
What thermal resistance does the NCP160BFCS514T2G exhibit in its WLCSP4 package?
In the WLCSP4 (Case 567JZ) package, the NCP160BFCS514T2G has a junction-to-ambient thermal resistance (RJA) of 108 °C/W when mounted on a JEDEC-standard board (JESD51-7). This value assumes proper PCB copper area and EPAD connection to ground - actual RJA improves with larger thermal pads and 2 oz copper layers (see Figure 53, page 15).
