Pennant was given an eight-week sentence, suspended for 12 months, after admitting drink driving, driving while disqualified and driving without insurance.
He was disqualified from driving for three years and ordered to pay costs at Trafford Magistrates Court.
Earlier, Pennant admitted drink-driving home from a nightclub after being dumped by text message by his girlfriend.
The Stoke player was more than twice the limit when he got behind the wheel of his BMW to drive back from Manchester in the early hours of April 29, the Court heard.
The 29-year-old was "depressed and stressed" after months of turmoil in his private life and suffering taunts while in the nightclub, it was claimed.
Pennant had been playing football earlier that day and had arranged for his estranged partner and their 20-month-old child to come and see him perform but they did not turn up. After suffering that blow, when he got home he found his new girlfriend had taken all her belongings and he received a text message telling him their relationship was over.
Depressed and home alone he accepted an invitation from friends to go to a nightclub in Manchester, but while there he became "distressed" because of comments circulating about his former partner, his lawyer Mike Stephenson said in mitigation.
This "broke the camel's back" and Pennant, unable to book a hotel room in central Manchester, decided to drive home.
He was arrested in the early hours of the morning after being involved in a minor road crash. The defendant may have been speeding and gone through a red light, the court heard, but he was not prosecuted over the accident.
Pennant was breathalysed and gave a reading of 89mcg of alcohol in 100ml of breath. The legal limit is 35mcg.
Pennant, of Tool Lane, Sandbach, Cheshire, had already been banned from driving earlier that month by JPs in Cannock, Staffordshire, for totting up too many points on his licence.
In the latest case, he admitted drink-driving, driving while disqualified and driving without insurance.
