Product details
Overview
MP2016DJ-LF-P from Monolithic Power Systems is a low-power adjustable-output linear regulator designed for high-voltage battery-powered systems. It operates across 4V–42V input, delivers up to 30mA continuous output (50mA peak), maintains ±2% output accuracy, and achieves <1.5µA shutdown current. Used in smart-battery packs and handheld devices requiring stable low-quiescent regulation.
For engineers reviewing the MP2016DJ-LF-P datasheet, MP2016DJ-LF-P pinout, MP2016DJ-LF-P application, or MP2016DJ-LF-P equivalent, key selection criteria include its 12µA quiescent current, 1.2V–40V adjustable output via resistor divider, thermal shutdown protection, and TSOT23-5 package compatibility with space-constrained portable designs.
Technical Context
The MP2016DJ-LF-P implements an external-feedback linear regulation architecture with a precision 1.23V reference at the FB pin. Its pass transistor supports dropout as low as 700mV at 30mA load, enabling operation near battery end-of-discharge voltages.
It integrates logic-level shutdown control (VIH = 1.8V, VIL = 0.22V), internal current limiting (50mA peak), and thermal shutdown with +150°C trip point and +20°C hysteresis-ensuring robust fault handling in unregulated high-voltage environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 42V - supports wide-range industrial and automotive batteries without pre-regulation. |
| Output Voltage Range | 1.2V to 40V - set externally via resistor divider; enables single BOM for multiple output rails. |
| Quiescent Current | 12µA - minimizes standby power loss in always-on battery systems. |
| Shutdown Current | <1.5µA - extends shelf life and runtime in deep-sleep modes. |
| Output Accuracy | ±2% - ensures reliable voltage margining for downstream analog and mixed-signal circuitry. |
| PSRR | 50dB (DC) - suppresses ripple from noisy high-voltage sources like DC-DC converters or chargers. |
| Thermal Shutdown Threshold | +150°C with +20°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design. |
Pinout & Package
MP2016DJ-LF-P is housed in a RoHS-compliant TSOT23-5 package (2.9mm × 1.6mm × 1.0mm), optimized for compact portable electronics. The exposed pad is not present in this variant (QFN-8 has exposed pad; TSOT23-5 does not).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply connection (4V–42V); requires ≥1µF X5R/X7R ceramic bypass capacitor. |
| 2 | GND | Power ground reference; must be low-impedance connection to system ground plane. |
| 3 | OUT | Regulated output node; drives load up to 30mA continuous with ≤900mV dropout. |
| 4 | FB | Feedback input referenced to 1.23V; sets output via R1/R2 divider (R2 = 250kΩ typical). |
| 5 | SHDN | Active-high enable control; logic HIGH ≥1.8V enables regulator; LOW <0.22V disables with <1.5µA draw. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Input Range | 4V–42V operation eliminates need for upstream buck converter in 12V/24V/36V battery systems. |
| Ultra-Low Quiescent Current | 12µA typical supply current enables >1-year battery life in 10µA-load IoT sensors. |
| Adjustable Output | 1.2V–40V range via two-resistor feedback allows reuse across diverse subsystems (e.g., 3.3V MCU, 12V sensor, 24V interface). |
| Integrated Protection | Thermal shutdown + current limiting prevent failure during short-circuit or overtemperature events without external components. |
| Small Footprint | TSOT23-5 package occupies <4.7mm² PCB area-critical for wearables and compact medical devices. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar adjustable-output linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Texas Instruments TPS7A4700RGWR | 20V max input, 1µA IQ, 1.2V–20V adj, SOIC-8 package (4.9mm × 6.0mm) | Lacks 42V rating; unsuitable for >20V battery systems; better PSRR (70dB @1kHz) but larger footprint | Select when ultra-low noise (4.7µVRMS) and higher PSRR outweigh input voltage and size constraints. |
| Analog Devices ADM7172ACPZ-R7 | 36V max input, 1.2mA IQ, 1.2V–36V adj, LFCSP-8 (3mm × 3mm) | Higher quiescent current limits battery life; no shutdown pin; requires external soft-start | Choose only if integrated soft-start and 36V capability suffice and shutdown control is handled externally. |
Compared with TPS7A4700RGWR and ADM7172ACPZ-R7, MP2016DJ-LF-P uniquely balances 42V operation, sub-15µA quiescent current, and TSOT23-5 size-making it the only viable option for space-limited, high-voltage battery-powered devices needing true shutdown control.

FAQ
What is the minimum recommended output capacitor for stable operation?
The MP2016DJ-LF-P requires a minimum 1µF X5R or X7R ceramic capacitor on the output. Using 4.7µF improves load transient response and reduces output noise, especially in ADC-supply applications. Avoid Y5V dielectrics due to large capacitance drift over temperature.
Can the MP2016DJ-LF-P be used without the SHDN pin connected?
Yes. Leaving SHDN open or connecting it directly to VIN enables automatic startup. However, tying SHDN to VIN removes the ability to externally disable the regulator-so this configuration forfeits shutdown control and increases system-level power management flexibility.
How is output voltage accuracy affected by temperature?
Over –40°C to +85°C, the FB pin reference varies from 1.181V to 1.279V (±2% total). Combined with resistor tolerance, this results in typical output voltage drift of ±3% across temperature-verified in production testing per the datasheet's electrical characteristics table.
Does the MP2016DJ-LF-P require an input capacitor?
Yes. A 1µF–10µF X5R/X7R ceramic capacitor between VIN and GND is mandatory for stability and line transient suppression. Larger values (e.g., 4.7µF) improve rejection of high-frequency noise from upstream sources like switching chargers.
What happens during thermal shutdown?
When junction temperature exceeds +150°C, the IC disables the pass transistor and enters thermal shutdown. Output drops to zero, and supply current falls below 10µA. The device automatically recovers once the die cools by at least 20°C-no external reset required.
Is the TSOT23-5 package lead-free and RoHS compliant?
Yes. The "-LF" suffix in MP2016DJ-LF-P explicitly denotes lead-free, RoHS-compliant packaging per EU Directive 2011/65/EU, with all solderable terminations meeting JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) requirements.
Can the MP2016DJ-LF-P drive capacitive loads greater than 10µF?
Yes, but stability must be verified. The datasheet specifies 0.23µF/mA minimum effective capacitance for stability. At 30mA, this implies ≥6.9µF minimum-so 10µF is acceptable. For >22µF, add a 22nF feed-forward capacitor across R1 to maintain phase margin.
