30V, 100mA TinyPower TM HT75xx-7 LDO with Protections Features General Description • Low power consumption The HT75xx-7 is a low power high voltage series of regulators implemented in CMOS technology which has the advantages of low voltage drop and low quiescent current. They allow input voltages as high as 30V and are available with several fixed output voltages ranging from 2.1V to 12.0V. • Low voltage drop • Low temperature coefficient • High input voltage – up to 30V • Output voltage accuracy: tolerance ±2% • Over current protection When the CE input is low, a fast discharge path pulls the output voltage low via an internal pull-down resistor. An internal over-current protection circuit prevents the device from damage even if the output is shorted to ground. An over-temperature protection circuit ensures the device junction temperature will not exceed a temperature of 160°C. • Over temperature protection • Chip enable/disable function • Package types: TO92-3, SOT89-3, and SOT23-5 Applications • Battery-powered equipment • Communication equipment • Audio/Video equipment Selection Table Part No. Output Voltage HT7521-7 2.1V HT7523-7 2.3V HT7525-7 2.5V HT7527-7 2.7V HT7530-7 3.0V HT7533-7 3.3V HT7536-7 3.6V HT7540-7 4.0V HT7544-7 4.4V HT7550-7 5.0V HT7560-7 6.0V HT7570-7 7.0V HT7580-7 8.0V HT7590-7 9.0V HT75A0-7 10.0V HT75C0-7 12.0V Packages Markings TO92-3 SOT89-3 SOT23-5 75xx-7 marking for the TO92-3, SOT89-3 types 5xx7 for the SOT23-5 type Note: "xx" stands for output voltages.

External Circuit It is important that external capacitors are connected to both the input and output pins. For the input pin suitable bypass capacitors as shown in the application circuits should be connected especially in situations where a battery power source is used which may have a higher impedance. For the output pin, a suitable capacitor should also be connected especially in situations where the load is of a transient nature, in which case larger capacitor values should be selected to limit any output transient voltages. where TJ(MAX) is the maximum junction temperature, Ta is the ambient temperature and θJA is the junctionto-ambient thermal resistance of the IC package in degrees per watt. The following table shows the θJA values for various package types. 200°C/W TO92-3 200°C/W SOT23-5 500°C/W 0.2W (SOT23-5) 0.2 0 0 25 50 75 100 125 150 Ambient Temperature (oC) In practical applications the regulator may be called upon to provide both steady state and transient currents due to the transient nature of the load. Although the device may be working well within its limits with its steady state current, care must be taken with transient loads which may cause the current to rise close to its maximum current value. Care must be taken with transient loads and currents as this will result in device junction temperature rises which must not exceed the maximum junction temperature. With both steady state and transient currents, the important current to consider is the average or more precisely the RMS current which is the value of current that will appear as heat generated in the device. The following diagram shows how the average current relates to the transient currents. PD(MAX) = (TJ(MAX) – Ta) / θJA θJA value °C/W 0.5W (SOT89-3, TO92-3) 0.4 In order to keep the device within its operating limits and to maintain a regulated output voltage, the power dissipation of the device, given by P D, must not exceed the Maximum Power Dissipation, given by PD(MAX). Therefore PD ≤ PD(MAX). From the diagram it can be seen that almost all of this power is generated across the pass transistor which is acting like a variable resistor in series with the load to keep the output voltage constant. This generated power which will appear as heat, must never allow the device to exceed its maximum junction temperature. The maximum power dissipation depends on the thermal resistance of the package, the PCB layout, the rate of the surrounding airflow and the difference between the junction and ambient temperature. The maximum power dissipation can be calculated using the following formula: SOT89-3 0.6 Power Dissipation Calculation Thermal Considerations Package 0.8 For maximum operating rating conditions, the maximum junction temperature is 150°C. However, it is recommended that the maximum junction temperature does not exceed 125°C during normal operation to maintain an adequate margin for device reliability. The derating curves of different packages for maximum power dissipation are as follows: ILOAD ILOAD(AVG) Time Rev. 1.10 17 February 18, 2016 HT75xx-7 As the quiescent current of the device is very small it can generally be ignored and as a result the input current can be assumed to be equal to the output current. Therefore the power dissipation of the device, PD, can be calculated as the voltage drop across the input and output multiplied by the current, given by the equation, PD = (VIN – VOUT) × IIN. As the input current is also equal to the load current the power dissipation PD = (VIN – VOUT) × ILOAD. However, with transient load currents, PD = (VIN – VOUT) × ILOAD(AVG) as shown in the figure.
