ap7363 1.5a, low quiescent current, fast transient ultra-low dropout linear regulator ap7363 document number: ds35059 rev. 2 - 2 8 of 14 www.diodes.com july 2011 ? diodes incorporated new product application note (cont.) no load stability other than external resistor divider, no minimum load is required to keep the device stable. the device will remain stable and regulated in no load condition. stability and phase margin any regulator which operates using a feedback loop must be compensated in such a way as to ensure adequate phase margin, which is defined as the difference between the phase shift and -180 degrees at the frequency where the loop gain crosses unity (0 db). for most ldo regulators, the esr of the out put capacitor is required to create a zero to add enough phase lead to ensure stable operation. the ap7362 has a internal compensation circuit which maintains phas e margin rega rdless of the esr of the output capacitor, any type of capacitos can be used. below two charts show the gain/phase plot of the ap7362 with an output of 1.2v, 10 f ceramic output capacitor, delivering 1.5a load current and no load. it can be seen the phase margin is about 90 (which is very stable) . short circuit protection when output current at out pin is higher than current limit threshold, the current limit protection will be triggered and clamp the output current to prevent over- current and to protect the regulator from damage due to overheating. thermal shutdown protection thermal protection disables the output when the junction temperature rises to approximately +170c, allowing the device to cool down. when the junction temperature reduces to approximately +160c the output circuitry is enabled again. depending on power dissipation, thermal resistance, and ambient te mperature, the thermal protection circuit may cycle on and off. this cycling limits the heat dissipation of the r egulator, protecting it from damage due to overheating. low quiescent current the ap7362, consuming only around 0.5ma for all input range, provides great power saving in portable and low power applications. -120 -100 -80 -60 -40 -20 0 20 40 60 80 100 120 frequency(hz) -80 -60 -40 -20 0 20 40 60 80 100 120 140 phase margin( ) loop gain(db) 100 1k 10k 100k 1m v in =2.7v v out =1.2v i l =1.5a c out =10 f cer gain phase gain-bandwidth plot for 1.5a load -120 -100 -80 -60 -40 -20 0 20 40 60 80 100 120 frequency(hz) -80 -60 -40 -20 0 20 40 60 80 100 120 140 phase margin( ) loop gain(db) 100 1k 10k 100k 1m v in =2.7v v out =1.2v i l =0a c out =10 f cer gain phase gain-bandwidth plot for no load
