Enpirion Power Datasheet EY1603 40V, Low Quiescent Current, 150mA Linear Regulator DS-1047 Datasheet The Altera® Enpirion® EY1603 is a wide input voltage range, low quiescent current linear regulator ideally suited for “always-on” and “keep alive” applications. The EY1603 operates from an input voltage of +6V to +40V under normal operating conditions and consumes only 18µA of quiescent current at no load. The EY1603 has an adjustable output voltage range from 2.5 to 12 V. The EY1603 features an EN pin that can be used to put the device into a low-quiescent current shutdown mode where it draws only 2µA of supply current. The device features automatic thermal shutdown and current limit protection. The EY1603 is rated over the -40°C to +125°C temperature range and is available in a 14 lead HTSSOP with an exposed pad package. TABLE 1.

The part is rated to operate over the -40°C to +125°C temperature range. Featuring ultra-low quiescent current, it is an ideal choice for “always-on” applications. It works well under a “load dump condition” where the input voltage could rise up to 40V. This LDO device also features current limit and thermal shutdown protection. Enable Control The EY1603 has an enable pin, which turns the device on when pulled high. When EN is low, the IC goes into shutdown mode and draws less than 2µA. In “always-on” applications, EN can be tied to IN. Current Limit Protection The EY1603 has internal current limiting functionality to protect the regulator during fault conditions. During current limit, the output sources a fixed amount of current largely independent of the output voltage. If the short or overload is removed from VOUT, the output returns to normal voltage regulation mode. Thermal Fault Protection In the event that the die temperature exceeds a typical value of +165°C, the output of the LDO will shut down until the die temperature cools down to a typical +145°C. The level of power dissipated, combined with the ambient temperature and the thermal impedance of the package, determines if the junction temperature exceeds the thermal shutdown temperature. See the “Power Dissipation” section on page 8 for more details. Application Information Input and Output Capacitors A minimum 0.1µF ceramic capacitor is recommended at the input for proper operation. For the output, a ceramic capacitor with a capacitance of 10µF is recommended for the EY1603 to maintain stability. The ground connection of the output capacitor should be routed directly to the GND pin of the device and also placed close to the IC. Output Voltage Setting The EY1603TI-ADJ output voltage is programmed using an external resistor divider as shown in Figure 11. VOUT VIN CIN 0.1µF R1 EN COUT 10µF VFB R2 GND FIGURE 11. OUTPUT VOLTAGE SETTING The output voltage is calculated using Equation 1: R1 V OUT = 1.223V ------- + 1 R2 (EQ. 1) Power Dissipation The junction temperature must not exceed the range specified in “Recommended Operating Conditions” on page 3. The power dissipation can be calculated using Equation 2: The maximum allowable junction temperature, TJ(MAX) and the maximum expected ambient temperature, TA(MAX) will determine the maximum allowable junction temperature rise (TJ), as shown in Equation 2: T J = T J MAX – T A MAX (EQ. 2) EY1603 40V, Low Quiescent Current, 150mA Linear Regulator 09619 February 2014 March 14, 2014 Altera Corporation Rev A Page 9 To calculate the maximum ambient operating temperature, use the junction-to-ambient thermal resistance (JA) as shown in Equation 3: T J MAX = P D MAX x JA + T A (EQ. 3) Board Layout Recommendations A good PCB layout is important to achieve expected performance. Consideration should be taken when placing the components and routing the trace to minimize the ground impedance and keep the parasitic inductance low. The input and output capacitors should have a good ground connection and be placed as close to the IC as possible. The feedback trace in the adjustable version should be away from other noisy traces. The 14 Ld HTSSOP package uses the copper area on the PCB as a heat-sink. The EPAD of this package must be soldered to the copper plane (GND plane) for effective heat dissipation.
