Product details

Overview

NCV8133BMX150TCG from onsemi is a 500 mA very low dropout (VLDO) CMOS voltage regulator with NMOS pass transistor and separate VBIAS supply, delivering fixed 1.5 V output at ±1.5% accuracy over −40°C to +125°C. It achieves 140 mV typical dropout at 500 mA, draws only 80 µA typical bias current, and supports stable operation with 2.2 µF ceramic output capacitance - ideal for automotive point-of-load regulation in FPGA/DSP power domains.

For engineers reviewing the NCV8133BMX150TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its dual-rail architecture (VIN/VBIAS), ultra-low dropout under high load, AEC-Q100 Grade 1 qualification, and XDFN6 1.2 mm × 1.2 mm package constraints for space-constrained PCB layouts.

Technical Context

The NCV8133BMX150TCG implements a dual-input NMOS-based VLDO architecture where VIN supplies the power path and VBIAS (2.4–5.5 V) powers internal control circuitry independently. This separation enables stable regulation even when VIN approaches VOUT, while minimizing bias current consumption (80 µA typ).

It features logic-level enable (VEN(H) = 0.9 V), thermal shutdown (160°C trip), undervoltage lockout on VBIAS (1.6 V hysteresis), and monotonic startup. The device is not equipped with active output discharge - confirmed by marking "BMX" (vs. "AMX") and absence of RDISCH specification in electrical characteristics.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 1.50 V ±1.5% over −40°C to +125°C - ensures precise core voltage for 1.5 V FPGA I/O rails.
Max Output Current	500 mA continuous - supports mid-power digital loads without external heat sinking in XDFN6 package.
VIN Dropout Voltage	140 mV typ. at 500 mA - enables regulation from 1.64 V input, critical for post-regulation after buck converters.
VBIAS Range	2.4 V to 5.5 V - allows use of shared 3.3 V or 5 V bias rail across multiple regulators in automotive ECUs.
I_Q (Bias Current)	80 µA typ. at 2.7 V - minimizes standby power loss in always-on vehicle modules.
PSRR (VIN)	70 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters feeding VIN.
Stability	Guaranteed with 2.2 µF ceramic C_OUT - eliminates need for large tantalum or electrolytic capacitors.

Pinout & Package

XDFN6 1.2 mm × 1.2 mm, 0.4 mm pitch, exposed thermal pad (Case 711AT). Requires soldering pad to ground plane for thermal performance.

Pin/Terminal	Circuit Role	Design Meaning
1 - OUT	Regulated output	Delivers 1.5 V to load; connects directly to local ceramic capacitor without vias for stability.
2 - N/C	No connect	True no-connect; PCB traces may be routed but must not be bonded or loaded.
3 - EN	Enable control	Logic-high (>0.9 V) enables regulation; internal pull-down ensures default-off state if left floating.
4 - BIAS	Bias supply input	Powers internal reference and control circuits; monitored by UVLO with 1.6 V hysteresis.
5 - GND	Power ground	Common return for IN, OUT, BIAS, and EN; must be tied to thermal pad for R_JA = 170°C/W.
6 - IN	Main input supply	Accepts 0.8–5.5 V; dropout defined relative to OUT, enabling ultra-low input headroom operation.

Key Features

Feature	Design Value
Dual-rail NMOS architecture	Decouples power path (VIN) from control logic (VBIAS), enabling stable regulation at sub-100 mV headroom while reducing sensitivity to output capacitor ESR.
AEC-Q100 Grade 1 qualification	Validated for −40°C to +125°C ambient operation with PPAP capability - meets automotive module reliability requirements without derating.
Ultra-low bias current	80 µA typical I_BIAS enables >10-year battery life in always-on telematics modules powered from 12 V via LDO-biased 3.3 V rail.
Monotonic startup	Controlled VOUT ramp limits inrush current into downstream capacitive loads - prevents brownout during cold cranking in automotive systems.
Thermal shutdown with hysteresis	160°C trip / 140°C recovery prevents latch-up during transient overload, allowing self-recovery without system reset.

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-dropout, automotive-grade linear regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NCV8133BMX150T2G	Same die, alternate tape-and-reel packaging (5000 pcs/reel vs. 3000 pcs/reel); identical electrical specs and XDFN6 footprint.	No functional difference; used interchangeably in production where reel quantity aligns with SMT line feed requirements.	Select based on procurement volume and line setup efficiency - no design or layout impact.
TLV73315PDBVR	Single-rail 500 mA LDO (no VBIAS pin); 170 mV dropout at 500 mA; ±2% accuracy; no AEC-Q100 qualification.	Lacks dual-rail flexibility and automotive qualification; suitable only for non-safety-critical consumer or industrial designs.	Choose only for cost-sensitive, non-automotive applications where VBIAS independence and Grade 1 temp range are unnecessary.

Compared with NCV8133BMX150TCG, the NCV8133BMX150T2G offers identical performance in a different packaging configuration, while the TLV73315PDBVR trades dual-rail optimization and automotive qualification for lower unit cost in commercial applications - making the NCV8133BMX150TCG the sole choice for AEC-Q100-compliant 1.5 V POL regulation.

FAQ

What is the output voltage tolerance of the NCV8133BMX150TCG over temperature?

The NCV8133BMX150TCG delivers 1.50 V output with ±1.5% accuracy across the full −40°C to +125°C junction temperature range, and tighter ±0.5% tolerance at 25°C. This is verified per AEC-Q100 stress testing and documented in the Electrical Characteristics table of the official datasheet (Rev. 2, September 2022).

Does the NCV8133BMX150TCG include active output discharge functionality?

No, the NCV8133BMX150TCG does not include active output discharge. Its marking suffix "BMX" (not "AMX") and absence of R_DISCH specification in the Electrical Characteristics confirm it lacks the internal pull-down transistor. Only NCV8133A-series variants provide this feature.

What is the minimum required VBIAS voltage for the NCV8133BMX150TCG at 1.5 V output?

The minimum VBIAS voltage for the NCV8133BMX150TCG is (V_OUT + 1.4 V) ≥ 2.4 V, i.e., 2.9 V. This ensures proper operation of internal control circuitry and avoids UVLO activation, as specified in the Recommended Operating Conditions table.

Can the NCV8133BMX150TCG operate with an input voltage lower than its output voltage?

No - the NCV8133BMX150TCG requires VIN ≥ VOUT + VDO (140 mV typ. at 500 mA), so minimum VIN is ~1.64 V. It cannot regulate when VIN < VOUT; however, its ultra-low dropout enables operation with minimal headroom unlike standard PMOS LDOs.

Is the NCV8133BMX150TCG compatible with 2.2 µF ceramic output capacitors?

Yes, the NCV8133BMX150TCG is explicitly characterized and guaranteed stable with 2.2 µF ceramic output capacitors (effective capacitance), as stated in both the Features list and Applications Information section - eliminating need for larger or higher-ESR alternatives.
