MAX17651 4V to 60V, 100mA, Ultra-Low Quiescent Current, Linear Regulator General Description The MAX17651 ultra-low quiescent current, high-voltage linear regulator is ideal for use in industrial and batteryoperated systems. The device operates from a 4V to 60V input voltage, delivers up to 100mA of load current, and consumes only 8μA of quiescent current at no load. The device consumes only 0.9μA current when in shutdown. Output voltage is adjustable in the 0.6V to 58V voltage range. Feedback voltage accuracy is ±2% over temperature. An open-drain, active-low PGOOD pin provides a powergood signal to the system upon achieving successful regulation of the output voltage. The device also incorporates an enable pin (EN) that allows the user to turn the part on or off. The device has a thermal shutdown feature that shuts down the part when the die temperature exceeds 165°C. The MAX17651 operates over the -40°C to +125°C industrial temperature range and is available in a 6 lead, compact TSOT and a 6-pin (3mm x 3mm) TDFN packages.

Block Diagram Detailed Description The MAX17651 ultra-low quiescent current, high-voltage linear regulator is ideal for use in industrial and batteryoperated systems. The device operates from a 4V to 60V input voltage, delivers up to 100mA of load current and consumes only 8μA of quiescent current at no load. The device consumes only 0.9μA current when in shutdown. Output voltage is adjustable from 0.6V to 58V voltage range. Feedback voltage accuracy is ±2% over temperature. An open-drain, active-low PGOOD pin provides a powergood signal to the system upon achieving successful regulation of the output voltage. The device also incorporates an enable pin (EN) that allows the user to turn the part on or off. The device has a thermal shutdown feature that shuts down the part when the die temperature exceeds 165°C. The MAX17651 operates over the -40°C to +125°C industrial temperature range and is available in a compact, 6-lead TSOT and a 6-pin (3mm x 3mm) TDFN packages. EN Input EN is an active-high, logic-level enable input that turns the device on or off. Drive EN high to turn the device on. While in shutdown, the device consumes only 0.9μA (typ). www.analog.com EN withstands voltages up to VIN + 0.3V, allowing it to be driven by high input-level voltages, or be connected to IN for always-on operation. Thermal Protection When the junction temperature exceeds +165°C, an internal thermal sensor turns the pass transistor off, allowing the device to cool. The thermal sensor turns the pass transistor on again after the junction temperature cools by 15°C. This results in a cycled output during continuous thermal-overload conditions. Thermal protection protects the MAX17651 in the event of fault conditions. Output Short-Circuit Current Limit The MAX17651 features a 140mA (typ) current limit. The output can be shorted to GND for an indefinite period without damage to the device. During a short-circuit event, the power dissipated across the internal pass transistor can quickly heat the device. When the die temperature reaches +165°C, the MAX17651 shuts down and automatically restarts once the die temperature cools by 15°C. Analog Devices │  7 MAX17651 4V to 60V, 100mA, Ultra-Low Quiescent Current, Linear Regulator Applications Information Available Output Current Calculation Output Voltage Setting The output voltage can be programmed from 0.6V to 58V. Set the output voltage by connecting a resistor divider from output to FB to GND. Choose R2 = 59kΩ, then calculate R1 with the following equation: R1 = 98.3 x (VOUT - 0.6)kΩ Output Capacitor Selection If the output voltage is less than 1.8V, use a low-ESR 10µF(min) 0805 ceramic output capacitor for good load transient response. If the output voltage is greater than or equal to 1.8V, use a low-ESR 4.7µF(min) 0805 ceramic output capacitor. At a particular operating condition, the power loss that leads to the temperature rise of the part is estimated as follows: PLOSS = (VIN - VOUT) x ILOAD where VIN is the input voltage, VOUT is the output voltage, and ILOAD is the load current. For a multilayer board, the thermal performance metrics for the packages are given below: θJA = 42°C/W for TDFN package θJA = 110°C/W for TSOT package The junction temperature of the MAX17651 can be estimated at any given maximum ambient temperature (TA_MAX) from the equation below: TJ = TA_MAX + (θJA x PLOSS) Junction temperature greater than +125°C degrades operating lifetimes. Calculate the maximum allowable output current, using the following formula: VOUT R1 FB ILOAD (MAX) = R2 (125 − T A _MAX ) θ JA × (VIN − VOUT ) Example: TA_MAX = +70°C, VIN = 24V, VOUT = 5V, θJA = 42°C/W for TDFN package GND = ILOAD (MAX) Figure 2.
