Voltage Regulator
output voltage controlled comparing portion internal reference driving pass transistor accordingly. control loop stability depends output capacitor load current, chip temperature poles/zeros introduced integrated circuit. ensure stable operation, output capacitor's capacitance equivalent series resistor requirements given table "Functional Range" Page have maintained. details also typical performance graph "Output Capacitor Series Resistor ESR(CQ) versus Output Current Page output capacitor also buffer load steps should sized according application's needs. input capacitor strongly recommended compensate line influences. Connect capacitors close component's terminals. protection circuitry prevent well application from destruction case catastrophic events. These safeguards contain output current limitation, reverse polarity protection well thermal shutdown case overtemperature. order avoid excessive power dissipation that could never handled pass element package, maximum output current decreased input voltages above thermal shutdown circuit prevents from immediate destruction under fault conditions (e.g. output continuously short-circuited) switching power stage. After chip cooled down, regulator restarts. This leads oscillatory behaviour output voltage until fault removed. However, junction temperatures above outside maximum ratings therefore significantly reduce IC's lifetime. TLE42754 allows negative supply voltage. this fault condition, small currents flowing into increasing junction temperature. This considered thermal design, respecting that thermal protection circuit operating during reverse polarity conditions.

Reset Function
reset function provides several features: Output Undervoltage Reset: output undervoltage condition indicated setting Reset Output "low". This signal might used reset microcontroller during supply voltage. Power-On Reset Delay Time: power-on reset delay time allows microcontoller oscillator start This delay time time frame from exceeding reset switching threshold until reset released switching reset output "RO" from "low" "high". power-on reset delay time defined external delay capacitor connected charged delay capacitor charge current ID,ch starting from application needs power-on reset delay time different from value given Item 5.3.6, delay capacitor's value derived from specified values Item 5.3.6 desired power-on delay time:
47nF
with
capacitance delay capacitor chosen trd,new: desired power-on reset delay time trd: power-on reset delay time specified this datasheet
precise calculation also take delay capacitor's tolerance into consideration. Reset Reaction Time: reset reaction time avoids that short undervoltage spikes trigger unwanted reset "low" signal. reset reaction rime considers internal reaction time trr,int discharge time trr,d defined external delay capacitor (see typical performance graph details). Hence, total reset reaction time becomes:
with
trr: reset reaction time trr,int: internal reset reaction time trr,d: reset discharge
Reset Output Pull-Up Resistor RRO: Reset Output open collector output requiring external pull-up resistor voltage VIO, e.g. Table "Electrical Characteristics Reset Function" Page minimum value external resistor given case connected voltage pull-up resistor shall connected voltage following formula:
