Product details
Overview
The MAX6160EUS+T from Maxim Integrated is an adjustable, low-dropout, micropower three-terminal voltage reference with output programmable from 1.23V to (VIN − 0.2V), 200mV dropout, 75μA supply current independent of input voltage, and ±1% initial accuracy over −40°C to +85°C - used in precision ADC/DAC biasing and portable instrumentation.
For engineers reviewing the MAX6160EUS+T datasheet, MAX6160EUS+T pinout, MAX6160EUS+T application, or MAX6160EUS+T equivalent, key selection criteria include its adjustable output range, ultra-low quiescent current stability across VIN, 100ppm/°C max temperature coefficient, SOT143-4 package footprint, and compatibility with capacitive loads up to 10nF without external compensation.
Technical Context
The MAX6160EUS+T implements a bandgap-based reference core with an internal 1.23V ADJ feedback threshold and programmable output via external resistor divider. Its supply current remains stable across input voltages from 2.7V to 12.6V due to regulated biasing, eliminating battery-current waste common in two-terminal references.
It features a dedicated ADJ pin that draws only 70nA at 1.23V, enabling high-impedance resistor networks for precise output setting. The device achieves stability with any capacitive load ≤10nF and delivers 15ppm/°C typical temperature coefficient (100ppm/°C max) over full operating temperature range.
Key Specifications

|---|---|
| Output Range | 1.23V to (VIN − 0.2V); enables flexible rail-to-rail referenced biasing in 3V/5V systems |
| Dropout Voltage | 200mV at 1mA; supports operation with minimal headroom, e.g., 2.7V IN → 2.5V OUT |
| Supply Current | 75μA at +25°C, ≤130μA over −40°C to +85°C; stable vs. VIN, extending battery life |
| Tempco | 15ppm/°C typical, 100ppm/°C max; ensures <±0.1% output drift over full temperature range |
| ADJ Threshold | 1.23V ±0.5%; sets precision feedback point for resistor-divider programming |
| ADJ Input Current | 70nA at VADJ = 1.23V; allows use of >200kΩ resistors without significant error |

Pinout & Package
The MAX6160EUS+T is housed in a RoHS-compliant 4-pin SOT143-4 package (3.0mm × 1.6mm × 1.1mm), optimized for space-constrained portable applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 2.7V to 12.6V; must exceed VOUT by ≥200mV for regulation |
| 2 (OUT) | Reference output | Programmable voltage node; sources/sinks up to 1mA with <1mV/mA load regulation |
| 3 (GND) | Analog ground reference | Low-impedance return path; must be connected directly to system ground plane |
| 4 (ADJ) | Feedback input | 1.23V threshold node; connects to resistor divider midpoint for output programming |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable output architecture | Enables single BOM part to support multiple reference voltages (1.23V–12.4V) via external R1/R2 |
| VIN-independent supply current | 75μA ±25μA over 2.7V–12.6V input range; eliminates input-voltage-induced battery drain variation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar adjustable voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1019CS8-2.5#PBF | Fixed 2.5V output; 20ppm/°C max tempco; 35μA IQ; SO-8 package | Lacks adjustability; suited only where 2.5V is sufficient and board space allows SO-8 | Select when fixed output simplifies design and lower IQ outweighs loss of flexibility |
| REF5025IDR | Fixed 2.5V output; 3ppm/°C max tempco; 950μA IQ; SO-8 package | Higher precision but 12× higher supply current; requires larger input headroom | Select only when sub-10ppm/°C stability is mandatory and power budget permits |
Compared with LT1019CS8-2.5#PBF and REF5025IDR, the MAX6160EUS+T uniquely balances adjustability, ultra-low power (75μA), and SOT143-4 compactness - making it optimal for battery-operated, multi-voltage systems where BOM consolidation and PCB area are critical.

FAQ
What output voltage range does the MAX6160EUS+T support?
The MAX6160EUS+T supports an adjustable output voltage from 1.23V up to (VIN − 0.2V), with VIN ranging from 2.7V to 12.6V. This means at minimum input (2.7V), the maximum output is 2.5V; at 5V input, output can reach 4.8V. The 1.23V ADJ threshold and external resistor divider enable precise setting across this full range, validated per the MAX6160EUS+T datasheet's Figure 1 and electrical characteristics table.
How does the MAX6160EUS+T achieve supply current independence from input voltage?
The MAX6160EUS+T uses an internally regulated bias network that maintains constant current draw regardless of VIN between 2.7V and 12.6V. Measured quiescent current is 75μA at +25°C and stays within 130μA across temperature and input range - unlike two-terminal references that waste battery current. This behavior is confirmed in the MAX6160EUS+T's Electrical Characteristics table and Typical Operating Characteristics plots (toc01, toc02).
What is the maximum capacitive load the MAX6160EUS+T can drive stably?
The MAX6160EUS+T is guaranteed stable with any capacitive load from 0nF to 10nF on its OUT pin, as stated in the "Stable for All Capacitive Loads up to 10nF" feature and verified in stability testing. No output capacitor is required, and adding one beyond 10nF may degrade transient response or cause oscillation. This specification applies directly to the MAX6160EUS+T in SOT143-4 configuration per the official datasheet.
Can the MAX6160EUS+T replace fixed-output references like the MAX6141 in existing designs?
The MAX6160EUS+T cannot serve as a direct drop-in replacement for fixed-output references such as the MAX6141 because it requires external resistors (R1/R2) to set output voltage and uses a different 4-pin SOT143 package versus the MAX6141's 3-pin SOT23. However, it offers functional equivalence for adjustable applications - with identical 200mV dropout, 75μA IQ, and −40°C to +85°C rating - provided the PCB layout accommodates the ADJ pin and resistor network.
What is the guaranteed temperature coefficient for the MAX6160EUS+T?
The MAX6160EUS+T has a guaranteed maximum temperature coefficient of 100ppm/°C over the full −40°C to +85°C operating range, with 15ppm/°C typical performance. This value is explicitly specified in the "Electrical Characteristics-MAX6160" table under "Output Voltage Temperature Coefficient (TCVOUT)" and distinguishes it from other MAX61xx variants (e.g., MAX6141 limited to 50ppm/°C max). It reflects worst-case drift relative to +25°C output.
