Product details
Overview
NX1117C120Z,115 from NXP Semiconductors is a 1.2 V fixed-output, ±1 % accuracy, low-dropout linear voltage regulator in SOT223 package, delivering up to 1 A output current with dropout voltage as low as 0.95 V at 100 mA, thermal shutdown, SOA control, and operation from −40 °C to 125 °C - used for post-regulation after DC-DC converters in USB devices and hard drive controllers.
For engineers reviewing the NX1117C120Z,115 datasheet, NX1117C120Z,115 pinout, NX1117C120Z,115 application, or NX1117C120Z,115 equivalent, this page delivers verified specifications, SOT223 terminal mapping, real-world use scenarios in point-of-load regulation, and validated alternative parts for design continuity and supply resilience.
Technical Context
The NX1117C120Z,115 implements internal reference-based feedback with SOA control that dynamically limits output current under high VIN–VOUT differentials to prevent thermal runaway. It requires no minimum load for regulation and maintains stability with 680 nF input/output capacitors in series with 1 Ω ESR.
Its architecture supports fast transient response (e.g., <±20 mV line/load step deviation), 72 dB PSRR at 120 Hz, and RMS output noise of 0.003 % (10 Hz–10 kHz), making it suitable for noise-sensitive analog and digital loads powered from switching supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.200 V ±1 % (1.176–1.224 V over full temperature and load range) |
| Max Output Current | 1 A continuous - sufficient for powering core logic, FPGAs, or microcontrollers at point-of-load |
| Dropout Voltage | 0.95 V typical at 100 mA; 1.07 V typical at 800 mA - enables operation with small VIN–VOUT margin |
| Quiescent Current | 5–6 mA at VIN = 11.2 V - low static consumption for always-on subsystems |
| PSRR | 72 dB at 120 Hz - suppresses ripple from upstream switching regulators |
| Operating Temp | −40 °C to +125 °C junction - qualified for industrial and automotive under-hood environments |
| Thermal Shutdown | Activates at 135 °C - protects against sustained overload or poor PCB heatsinking |
Pinout & Package
SOT223 (SC-73) plastic surface-mount package with integrated heat sink pad; 4-terminal configuration optimized for medium-power linear regulation and thermal dissipation on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference and thermal path - connected to large copper pour for thermal management |
| 2 | VOUT | Main regulated output - connects directly to load and local bypass capacitor |
| 3 | VIN | Unregulated input - must be ≥2.6 V and ≤20 V; decoupled with 680 nF ceramic capacitor |
| 4 | VOUT | Second output connection - paralleled with Pin 2 to reduce trace resistance and improve current sharing |
Key Features
| Feature | Design Value |
|---|---|
| No minimum load requirement | Enables stable regulation down to 0 mA output - ideal for standby or sleep-mode circuits |
| SOA control | Prevents thermal failure during high VIN–VOUT conditions by limiting IOUT before junction overheating |
| Wide input range (up to 20 V) | Supports direct connection to 12 V or 15 V rails without pre-regulation |
| Low output voltage drift | 0.7 % variation over −40 °C to +125 °C ambient - ensures consistent system timing and logic thresholds |
| Robust ESD rating | 2 kV HBM - reduces risk of handling damage during assembly and test |
Applications
| USB Power Delivery Module | Hard Drive Controller Board |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1117-12CDR | ±2 % output accuracy; 1.2 V fixed; 800 mA max output; SOA not specified | Limited to commercial temperature range (0 °C to 125 °C); lower PSRR (60 dB) | Acceptable for cost-sensitive consumer designs where ±1 % accuracy and extended temp are not required |
| LD1117S12TR | ±2 % accuracy; 1.2 V fixed; 800 mA max; thermal shutdown only (no SOA control) | Lower ESD rating (1.5 kV HBM); higher dropout (1.1 V typ. @ 800 mA) | Suitable for legacy industrial designs with existing LD1117 footprint; verify thermal margin without SOA protection |
Compared with TLV1117-12CDR and LD1117S12TR, NX1117C120Z,115 provides tighter output accuracy, full industrial temperature support, SOA control for robustness under variable input conditions, and superior PSRR - making it preferred for mission-critical embedded systems requiring long-term stability and thermal resilience.

FAQ
What is the maximum input voltage rating for NX1117C120Z,115?
The absolute maximum input voltage for NX1117C120Z,115 is 20 V, per the Absolute Maximum Ratings table. For reliable operation, the recommended input range is 2.6 V to 11.2 V when delivering 1.2 V output - ensuring adequate headroom for dropout and thermal management. Exceeding 20 V risks permanent device damage.
Does NX1117C120Z,115 require an external capacitor for stability?
Yes, NX1117C120Z,115 requires both input and output capacitors: 680 nF ceramic capacitors in series with 1 Ω ESR are specified for stable operation and optimal transient response. Omitting or undersizing these capacitors may cause oscillation or excessive output voltage deviation during load steps.
Is NX1117C120Z,115 pin-compatible with other 1.2 V LDOs in SOT223?
No - while NX1117C120Z,115 uses the standard SOT223 pinout (GND, VOUT, VIN, VOUT), its SOA control circuitry and ±1 % accuracy specification differ from generic SOT223 LDOs like LD1117 or AMS1117. Direct substitution requires validation of thermal behavior, PSRR, and load-step performance in the target application.
What is the thermal resistance (Rth(j-a)) of NX1117C120Z,115 on a standard FR4 PCB?
When mounted on a standard FR4 PCB with single-sided copper and tin-plated finish, NX1117C120Z,115 has a typical junction-to-ambient thermal resistance of 150 K/W. With a 6 cm² output copper pad, Rth(j-a) improves to 72 K/W - enabling higher continuous current capability without exceeding 125 °C junction temperature.
Can NX1117C120Z,115 be used without a heatsink in a sealed enclosure?
Yes - NX1117C120Z,115 can operate without an external heatsink if PCB layout provides adequate copper area (≥6 cm² thermal pad) and ambient temperature remains ≤70 °C at full 1 A load. At 125 °C ambient, derating to ≤500 mA is required per the power derating curves in the datasheet.
